Remembrance Challenge

Leave a comment

We took our cubs to the local war memorial in the Church just down the road from the Scout Hall. Before we went we”d got the cubs to make a wreath of poppies and to write a message on it. Each boy did his own personal wreath. We then went on a walk down the road and went into the Church where we spoke to them about why we remember and also how things were different back in 1914. South Merstham wasn”t as big then as it is now, for a start the new houses were mostly built in the 1950s. In the 1911 census there were somewhere in the region of 600 men in the locality, about 150 of whom signed up in August 1914 (I”m guessing some would be unfit, others in jobs that couldn”t just go off to war and some others not that keen).

Remembrance Challenge

At the end of the session we gave each of the cubs a slip of paper with one of the names from the WW1 memorial in the church and the Commonwealth War Graves Commission website. They were asked to come up with what they could about the name they were given. I took a name too, and being more grown up and a bit of an analyst I went a bit further than just the CWGC website. I didn”t pay for any information though, I only used free open sources.Why don”t you go down to your war memorial and do something similar. Post your findings on your favourite social media and challenge your friends.

Who was William English?

William English was born in Bletchingley in the Autumn of 1874, his father was Gordon English (who lived in South Merstham by 1918). In the summer of 1905 he married Catherine Colgate Dagnall in Reigate. Catherine was born in Reigate in the Summer of 1879 and her family is reasonably well documented on http://loiselden.com/tag/dagnall/.The search entry for the 1911 census (which I couldn”t see the whole record of without paying) showed that William was a caretaker in 1911. He seems to be in Reigate, although I couldn”t quite see the address details. His wife is listed as living at 14 Croydon Road in Reigate by CWGC, he may well have been living there at the time, or she could have moved after his enlistment.

War Service

William”s service number is G/450 and he is listed as an Acting Company Sergeant Major with the 7th (Service) Battalion of the Queen”s (Royal West Surrey) Regiment at the time of his death in May 1918.His regimental service number is very low, the series was used for the wartime volunteers and started in August 1914. This suggests that he was in the first batch of volunteers, although the battalion he served with is part of K2, or the second hundred thousand volunteers. Either way it is likely he was with the 7th (Service) Battalion (NB there was another 7th Bn of the Queen”s Regiment).

7th (Service) Battalion, Queen’s Regiment

Sept 1914 Formed at Guildford as part of the Second New Army (K2) and then moved to Purfleet to join the 55th Brigade of the 18th Division then moved to Colchester.

May 1915 Moved to Salisbury Plain.

27.07.1915 Mobilised for war and landed at Boulogne. This is the start of the Battalion war diary which has been digitised and you can read it online. The first entry lists all the officers and warrant officers with the battalion as well as the overall strength. William English was not a CSM at this stage.

The Battalion spent most of 1916 in the line or resting between spells at the front. It was one of the assault battalions on 1st July and while it took casualties these weren’t enough to stop it actively participating in The Battle of Albert, The Battle of Bazentin Ridge, The Battle of Delville Wood, The Battle of Thiepval Ridge, The Battle of the Ancre Heights, The Battle of the Ancre.

1917 was a similar pattern of operations with periods of rest, consolidation & training between spells in the front line trenches. Operations on the Ancre, The German retreat to the Hindenburg Line, The Third Battle of the Scarpe, The Battle of Pilkem Ridge, The Battle of Langemarck, First Battle of Passchendaele, The Second Battle of Passchendaele. Notably it took a pasting at Passchendaele and lost a lot of men.

In 1918 the battalion was in the line when the Michael offensive happened, and two companies were completely lost, in addition to casualties taken in the other companies that managed to retire. I’d surmise that this is when William English, as an Acting CSM, was captured by the Germans. I’d also guess that he was wounded when he was captured and this is what lead to his death in Germany on 9th May 1918.

It is possible that he was captured earlier and that there was some other cause of death, without seeing a death certificate or a service record (I looked and could not find his service record at all) it is difficult to be sure. I read the entire battalion war diary from when it starts in 1915 up to May 1918 and he isn’t mentioned once. The CSMs occasionally get a mention, usually when they are either replacing the RSM, leaving to be commissioned or running some instruction for junior officers.

Knowing that the role usually keeps them moving between the rear and the front when in action, and ensuring discipline and training in camp it is unlikely that a CSM would be taken prisoner except when the lines are fluid, which is during a large battle. CSMs don’t usually go out and patrol, they’re more likely to be checking sentries or that the rations and ammo have come up if they are in the trenches. In battle they may well be moving forwards to find where people are, which would make them more prone to capture. In a retirement they may not have been with the company when orders were given to retire and could easily turn up where the enemy now are.

CSM William English is listed as a Prisoner of War in the Queen’s Regiment archives, and he is buried in the Niederzwehren cemetery, Kasseler Stadtkreis, Hessen, Germany. This is a concentration cemetery bringing in graves from POWs from southern Germany.

That’s what I know. If you know more please drop me a comment.

Thanks.

Book Review – Zero Six Bravo by Damien Lewis

Zero Six Bravo: 60 Special Forces. 100,000 Enemy. The Explosive True StoryZero Six Bravo: 60 Special Forces. 100,000 Enemy. The Explosive True Story by Damien Lewis

My rating: 4 of 5 stars

I make a point of reading first hand accounts of special forces operations. I started with world war two tales of the SAS and have worked up to the present time. Since the Bravo Two Zero fiasco I don’t expect much from tales of recent events.

This particular book tells the tale of a Special Boat Service mission in Iraq in 2003. It suffers a bit from excessive hypebole, presumably to garner sales. However it is actually very readable, and although much of the outcome is telepgrahed in advance the way it’s done is through a good hook to keep you reading to find out the detail of how/what happens. Well before all the debates in Parliament in 2003 M Squadron SBS were training up for their mission, changing their role from maritime operations to being vehicle borne. They then went into Iraq just before the air war started in 2003 with an attempt to contact a major Iraqui army formation to persuade it to surrender.

You know when you start to read it that the mission isn’t going to go well. In fact without even knowing anything about it I picked up that it must have gone horribly wrong. However I also knew that it couldn’t have gone that far wrong, because otherwise I probably would have heard about it since I have an interest in current affairs and military operations.

The story follows the perspective of one SBS Sergeant who was the lead navigator for most of the mission. Mainly it focusses on what he sees, and the actions of his three man vehicle crew. On the whole it is an interesting narrative and it gripped me enough to read longer than I normally do.

There’s a clear thread running through it of the forebodings, that may well have been how the central character felt, but are laboured to the extent that it comes across as 20:20 hindsight. There are also some rather strained references to Bravo Two Zero and the similarities with that patrol (both seem to have been compromised because they refused to shoot a child goat herder). That doesn’t really wash with me because the goat incident in Bravo Two Zero wasn’t repeated in the other books about the patrol and The Real “Bravo Two Zero” gives another version of events (apparently two Iraqui veterans of the Iran-Iraq War spotted the patrol, not a child goat herder).

Despite this I still think it’s worth a read, especially if you get it for the knock down price of 99p as I did.

The 200 Foot General

2 Comments

This is the third post on my Operational Research driven wargame rules (and it’s probably about time that I came up with a catchy name for them, ideas in the comments section most welcome).

One of the most unrealistic things I find in most commercial wargames that I have read or played is that it is very easy for players to change their plans and give new orders to their troops every turn. This is so common that there’s even a name for it, the 200ft General.

What is the Problem?

The concept being that the player is like a General with perfect perception and control of his troops, and he can react to things that they aren’t yet aware of because the player can see the models on the table.

Here are a couple of relevant quotes from the Operational Research that demonstrate why this is a problem.

“a detailed, well-rehearsed plan blocks acceptance of the quick orders rattled out over the radio ten minutes before an attack starts. This mix of friction and mental block can be seen to play a part in nearly half of all mission failures.” Murray in Brains & Bullets

“complicated plans were much more likely to fail.” Murray in Brains & Bullets

So this gives a constraint to the game design. A successful OR driven wargame will ensure that it isn’t easy to change orders and that the more complicated a plan is the more likely it will be to fail.

Potential Solutions

This isn’t a new problem, many wargame designers have grappled with it over the decades that wargaming has been popular. Lots of games have mechanisms of one sort or another to counteract this, ranging from hidden movement and deployment through to complex activation systems. All of these have problems, but at least they’re trying to solve the core problem of limiting player decisions to those that are reasonable for a commander on the ground.

  • Hidden movement & Deployment. This is a very good solution, and one that lots of games try to implement. It has difficulties in that you either need to trust the other player or have an umpire. Failing that some pre-game organisation to produce maps that can be annotated helps. It tends not to be used for competition wargames.
  • Written Orders. This is what real armies do, and so far as I’m aware only one commercial game has attempted this (Spearhead). It slows down the game, or increases setup time. Possibly producing a pro-forma might speed things up.
  • Unit activations. This seems to be common in popular rules. The actual mechanisms vary considerably, but the gist of it is that as a player you cannot be sure whether or not particular units will be activated. About all you can be sure of is that you cannot move your entire army. A good example of this is the DBA PIP system. A general gets 1d6 unit activations each turn.

I think that a good solution would be streamlined and easy to implement by players. Something like this is likely to have a major impact on gameplay speed, and we’re looking for ‘fast’ as a default setting. Each game turn needs to take 5-10 minutes to run through so that a whole game (including setup) can happen in about 2 hours.

Do you have any other potential solutions to this problem?

2D Morale Chart

1 Comment

Further to the previous post Faith in Morale I’ve tried to synthesize the varioius readings on military psychology into a set of morale rules that might give a realistic ebb and flow to an engagement. I’ve not had a chance to test these yet, but here’s what the chart looks like.

v01 of the 2D Morale Chart, (c) 2014 James Kemp
v01 of the 2D Morale Chart, (c) 2014 James Kemp

Reading through the various OR type publications it seems to me that morale is affected by proximity to both friends and the enemy. The closer solders get to the enemy the more they seem to do things other than follow orders. This is not really a surprise, but it’s nice to see the research back up the gut feel.

Where I can find hard numbers for things I have used them to construct the 2D morale chart. In some ways this is sort of arbitrary, the numbers aren’t comprehensive enough to complete it. I’ve taken distance from the enemy as one axis and propensity to fight as the other axis. Probability isn’t as straightforwards as counting the squares, as I’ve chosen to use a 2d6 roll on this chart. This tends the answer towards 7 and I have used the probabilty of a given result (or greater) as the method for putting the shading on the boxes. Where certain conditions make something more or less likely the difference from the probability of 7 or more is what I’ve used to decide whether the die modifier would be +/- 1, 2 or 3 (most end up as +/-1).

I’ll post up more of this, along with some ideas on how I expect it to work, in a later post. Broadly though each glob of troops will have a marker on the chart showing their current morale state. Each time morale is tested they will roll 2d6 and modify. Scores of 6-8 (about 45%) will remain unchanged. scores of 9-11 will improve morale and 12 will improve it and move the unit closer to the enemy (except for defenders in prepared positions). Scores of 4 or 5 will decrease morale, a 2 or 3 will decrease morale and cause the soldiers to give ground back to cover.

Faith in Morale

8 Comments

An Army Padre in Afghanistan with a CrossI’ve been reading operational research on the psychology of combat recently. It got me to thinking about the role of religious faith in morale of soldiers. I’m not personally religious and don’t have an axe to grind on this. What I am trying to do is build a game design model that properly accounts for relevant factors.

The thought that struck me was that combat is very stressful and that soldiers are called on to do unpleasant things to others. This isn’t an every day thing but it does happen. The after effects can be very severe, PTSD isn’t pleasant for anyone and can last for years after the traumatic events have finished. Psychological casualties are as real as the physical ones, they just have a delayed onset and are harder to spot.

Faith in Morale

Looking at rational human reactions in combat and life threatening situations you can see that the belief system of the individual plays a strong part. If you read first hand accounts enough you begin to understand this. Heroes often do what they do because they don’t see other options that they find acceptable.  People run into burning buildings or stay at a point of danger to help others. A selfish rational view would get you out of there. This often comes down to helping other members of the in group, not letting others down or not being able to live with themselves if they hadn’t tried to help. It is rare to hear patriotism cited, although often modestly you’ll hear ‘I was just doing my job’. That last is rarely true from a technical perspective but it reveals that the person that said it was driven by their belief system.

You’ll have noticed that I’ve been writing about a belief system here rather than faith. That’s deliberate. Faith is a kind of belief system but isn’t all of it. Everyone has a belief system, even atheists. Not everyone has faith.

So where do belief systems come from?

They are a product of our upbringing and life experiences.  Religious faith has a major part in shaping them, as does the dominant culture in the society that we live in. Even those that consciously reject those are shaped by it in their rejection.

Some examples. Homophobia is driven by belief systems. The dominant culture in the UK has taught us that it is a bad thing. Some religious groups disagree, and there is a high level of support far that point of view from the older members of society and those that have arrived from other cultures that don’t share the same belief as our dominant culture.  In the main the driver for homophobia is the classic out group of psychology.  Humans form groups of similar outlooks and turn against other groups. It’s animal instinct and manifests in many places and in many ways. Civilised humans learn to control the behaviour it drives and accept that other people (mostly) aren’t a threat. Being indoctrinated from birth into thinking about things makes this much easier.

Back to combat. The fundamental beliefs that go on here are about harming others and self preservation.  Religion tends to have a view on both of these. Typically it is don’t harm others and you need to make earthly sacrifices for a heavenly reward.

The combat calculus every combatant goes through is pretty much ‘does the risk to me outweigh the benefits of what I’m doing?’

If you are an atheist with no belief in an afterlife then you aren’t going to be as keen on checking out as someone expecting a massive reward for furthering the cause of their chosen religion (and it is the individual combatant’s interpretation that counts here, not the orthodox view).

So perhaps you get something like this:

Belief harm to others self-preservation Overall result
Atheist Only if its within the rules of engagement I don’t want to die Avoids taking risks where possible, but is ready to kill to do the job at hand. Unlikely to operate outside the rules of engagement lest there is an earthly punishment.
Humanist Do unto others as you would have done to yourself I don’t want to die Kills only when there iis no alternative. Will stay well within the rules of engagement as it is what their belief system demands. Won’t take unnecessary risks but will do what they can to help others.
Orthodox Christian/Muslim Killing is wrong, but God accepts that sometimes it is necessary. I don’t want to die yet, but there will a reward in the afterlife if I do good work. As with the Humanist avoids harm to others, but if it him or me will kill the enemy. Will self-sacrifice to save/help others but tries where possible to preserve their ability to continue to act.
Religious Fanatic God wants me to kill unbelievers If I do God’s work I will be rewarded in the after life. Disregards personal safety to achieve the mission objective (which implictly includes doing what God demands and converting or killing the unbelievers.

Let me know what you think in the comments thread.

Brains and Bullets: How Psychology Wins WarsBrains and Bullets: How Psychology Wins Wars by Leo Murray

My rating: 5 of 5 stars

Brains and Bullets is an excellent and very readable book which tries to put some hard numbers on a variety of psychological tactics that can be used to persuade your own troops to fight and the enemy to give up.

This is an excellent work on what happens in combat and why. It is very readable, structured into bite sized chunks on the key phenomena and then some joining up when it has all been explained. Each chapter opens with an account from a real soldier who experienced that psychological effect in combat. This is then analysed and explained, pulling in other examples as required to show that it isn’t an isolated incident but a general effect. Those examples range from the Napoleonic Wars right up to operations in Afghanistan, and they’re the products of proper scientific research not just a collection of war stories from unreliable sources.

That said there is no need to be an operational researcher, or scientist to understand the book. The language used is straightforward and direct, each of the concepts is very well explained and it forms an excellent introductory work as well as being well researched. The target audience is ordinary people without a technical or military background (although the author hopes that many military officers and civil servants will read it and think about it). Here’s my favourite line from the end of the book “if you are paid to be a military analyst, don’t forget that you work for the Crown (or the people) and for soldiers. You owe no allegiance to your cost centre manager. Crack on.”

If you do have a serious interest then it is worth saying that this isn’t fluffy pop psychology (I like those as light reading, having read Psychology at uni). All the conclusions are backed up with hard numbers from years of solid operational research. The author is hoping to influence army officers to use tactical psychology to make them more effective, so for example “even the hardest-fought flank attack seized ground with a smaller force, captured more of the enemy and caused fewer fatalities on both sides. flanking attack was six times more effective than a frontal attack.”

I’m not going to summarise this book like I did for the Stress of Battle, it’s way more available and affordable. Go buy it yourself (or borrow from the Library) and enjoy it. I certainly did.

The Stress of Battle – Part 4 – Op Research on Anti-Tank Combat

This is the fourth part of my review of The stress of battle: quantifying human performance in combat by David Rowland, which is an essential piece of Operational Research on WW2 and Cold War combat operations. This part covers the findings on anti-tank combat.

Anti-Tank Combat

Unlike small arms, the effectiveness of weapons used for anti-tank combat has changed considerably over the course of the mid-20th century. From non-specialist gunfire in WW1, to high velocity armour piercing in WW2 and then to Anti-Tank Guided Weapons in the Cold War period. This makes the operational research on anti-tank combat harder to do because the start point needs to be battles where only one kind of AT weapon is in action. Much of the analysis on anti-tank combat starts with the ‘Snipe’ action during the second battle of El Alamein in North Africa where data on each of the guns individually was available.

  • ‘heroic performance’ plays a large factor in the effectiveness of anti-tank guns
  • about a quarter of guns (at most) performed heroically (including those where platoon, company or battalion level officers assisted with firing guns)

  •  rate of fire is proportionate to target availability (i.e. when there are multiple targets crews fire faster)
  • the median point for heroes was 0.3 tank casualties per gun, where for non-heroes it was 0.03 tank casualties per gun
  • tanks are less effective in defence than AT guns alone, or tanks supported by AT Guns
  • AT Guns with tanks apparently kill three times more tanks than the tanks would on their own
  • AT Gun performance is attributed to having a higher concentration of SNCOs and Officers with deployed ATG compared to tanks (about three times as many)
  • heroes were disproportionately represented by SNCOs and Officers (at least in terms of who got the medals), in 75% of cases an SNCO or Officer senior to the gun crew commander was involved
  • Paddy Griffith is quoted on tank casualties that “relatively few appeared to have been caused by enemy tanks”

Overall it shows that the biggest single effect in anti-tank combat was down to leadership. Where gun crews are well lead then they are significantly more effective in battle. This is assuming that the guns in question can have some effect on the tanks that they are shooting at, which was the case in all of the battles examined (including a mix where the guns defended successfully with those where the gun lines were overrun by tanks).

This is the third part of my extended review of The Stress of Battle by David Rowland. It is such a strong piece of operational research that I thought that it would be useful for wargame designers (and players) to understand what the research evidence is for what went on in WW2 battles.

Fighting in Woods

The data comes from an analysis of 120 battles that took place in woods or forests from the US Civil War to the Korean War. It also applied all the things from the previous research and tried to see how woods differed from combat in other types of terrain.

  • Defence is less effective in woods, most likely because limited fields of view mean that the engagement ranges are shorter
  • Combat degradation is greater in woods during night battles
  • Artillery suppression is less effective in woods (presumably because the trees absorb some of the shell splinters)
  • Attack casualties reduce with attacker experience (after ten battles attacker casualties are half of that of inexperienced troops)

Stress of Battle – Part 2 – Op Research on Urban Battles

This is the second part of my review of The stress of battle: quantifying human performance in combat by David Rowland, which is an essential piece of Operational Research on WW2 and Cold War combat operations.

For this part I thought that I would focus on the lessons on urban battles. Rowland and his team used historical analysis on lots of WW2 urban battles and then compared this to a series of field trials using laser attachments to small arms and tank main armaments in the late 1970s and early 1980s.  The approach was to find battles where single variables could be controlled, and then use them to work out what the effect of that variable was on outcomes.

Here’s an interesting table on how attacker casualties vary by odds and the density of defending machine guns. Interestingly, in successful assaults the defender casualties are constant.

The interesting thing for me is that training/experience counts for a lot, halving casualties. Also attacking with the conventional 3:1 odds for success increases the casualties that you suffer, without having any appreciable difference in those inflicted on the enemy (although it does make it more likely for succesful attacks with untrained/inexperienced troops).

The village has been named after the adjacent river, and all the street names are in Welsh, although it is most representative of an East European village. This area is not often open to the public. (Photo credit: Wikipedia)

Adding armour support makes a huge difference too. Although tanks in urban areas are more vulnerable if they lose their infantry support. However with infantry they significantly reduce attacker casualties.

  • Defence experience gave no detectable benefit to causing casualties, but attack experience does (in urban combat)
  • typically three times as many defenders will surrender (some wounded) as are killed or withdraw, the only sensitivity on this is being completely surrounded (so 20% dead, 60% captured (incl wounded) and 20% withdraw);
  • attack casualties are less affected by force ratio in urban attacks than in open counrtyside;
  • successful defence of urban areas is best achieved by light defence with counter attacks supported by armour

Rubble & Prepared Defences

This another area covered. There is a general increase in attacker casualties by about 50% when defenders are in rubble or prepared defences. The primary effect of rubble though is to slow down rates of advance.

  • Rubble halved the rate of advance compared to undamaged urban areas
  • maximum unopposed advance rates were about 800 metres per hour in urban areas (400m/hr for rubble)
  • Opposition slowed the advance by a factor of 7

An interesting aside on this was the relative effectiveness of different types of German Infantry. Parachute troops and Panzergrenadiers were reckoned to be tougher opponents than normal infantry. However the analysis showed that the extra stubbornness was a factor of the higher than normal allocation of MGs to those troops. The rate of attacker casualties per defence MG wasn’t significantly different.

Not exactly a book review, more of a synopsis of a great work of Operational Research by David Rowland. The Stress of Battle: Quantifying Human Performance in Combat is the end result of years of work by David Rowland and his team at the Ministry of Defence. Rowland was the father of historical analysis as a branch of Operational Research.

This particular work looks at a combination of field analysis experiments in the 1980s using lasers, well documented WW2 engagements and a handful of battles from other wars. Almost every page in it is packed with evidence or explanations of the complex methodology used to ensure that you could get controlled results from an otherwise messy and chaotic environment. If you are playing or designing wargames then this is one of the books that you absolutely must have on your book shelves (and have read too).

When I was reading the book I was often underlining or marking sections with post-it flags. In particular I drew the following interesting snippets from the book:

  • Tanks suppress defenders, but you need at least two tanks per defending MG to have any effect;
  • Combat degradation is about a factor of 10 compared to performance on firing ranges
  • Anti-tank guns focus the attention of tanks from suppressing MGs, and the bigger the anti-tank gun the more attention it diverts (unsurprisingly);
  • Fortifications & obstacles (i.e. properly prepared defensive positions) increase defence effectiveness by a factor of 1.65;
  • In defending against a 3:1 attack, the average rifleman will inflict 0.5 casualties on the attackers whereas a MG will inflict 4 casualties;
  • 1 in 8 riflemen will cause 4 casualties, and the other 7 none;
  • MG equivalents for casualty causing are: 9 rifles = 1 MG; 1 medium mortar (81mm) = 3 MG;
  • Combat effectiveness grows with experience, improving the casualty exchange ratio;

This is just a taster of what the book contains. Really worth reading. Not only that it is fantastically well illustrated with loads of graphs, diagrams and pictures from the field exercises to illustrate the points in the text.
