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 story of 9 RTR in WW2 written by one of its officers and including material from many of the survivors and contemporary diaries, including the battalion war diary, the brigade history and at one point the radio logs. It is packed with a wealth of material, much of which is directly quoted from a primary source. If you want a feel for what life was like for a heavy tank battalion then this is the book to read.

The stories told by the survivors and in the diaries don’t pull any punches, and some of what is described is quite horrific, many of the casualties in the battalion are well documented and the nature of the injuries suffered by tank crews tend to be severe.

The battalion re-formed in [late 1940/l941] and was one of the first to be equipped with Churchills. It trained in the UK until mid to late June 44 when it went to France. It took part in Goodwood & Epsom and the Falaise battles supporting the Canadians and 43rd Wessex Division at various stages. After that they were involved in the capture of Le Havre, Walcheren, and the Reichswald.

Each of the stages of the battalion’s existence and each of its battles forms a chapter. These are opened by the official account of what happened followed by personal narratives of events during the same period. Often the same incident is reported from several sources which gives you a clearer idea of what might have happened, and the level of confusion. For example one tank driver reported that he had no idea where he was during one operation as his vision slits were covered in mud and he was relying on the tank commander to guide him. At the end of the book are several appendices with a wealth of statistics and other information useful to gamers. Amongst other things the casualties are very well documented, not only in the usual table of numbers, but it also gives service number, rank, name, trade, appointment (e.g. troop leader’s driver), date, place, and sometimes a short description of the incident (e.g. mortar fragment in the face). There are also extracts from operational orders and most battles have several maps showing you the ground and the movements of the troops.

Overall I’d rate the book very highly and strongly recommend it to others that have an interest in WW2 and/or tank operations.

Taming the Panzers, Patrick Delaforce

Taming the Panzers: 3 RTR at War, 1914-45

This is a history of 3rd Royal Tank Regiment (a battalion sized unit for those not au fait with UK Armoured regiments). It starts with a chapter of their origins in the First World War and then their subsequent peacetime evolution. 3RTR fought in the 1940 France campaign at Calais, then in Greece in 1941 followed by the western desert. They returned to the UK in late 1943 and took part in the NW Europe campaign eventually meeting up with the Russians in the Baltic.

The Author was an artillery officer (with 13 RHA) who supported 3RTR in the NW Europe campaign and this gives him a connection to those that he has written about, much of the text is based on letters and conversations with the surviving officers and men of 3 RTR.

Synopsis

During the desperate days of May 1940 that ended with the fall of France, the 3rd Battalion Royal Tank Regiment was sent to Calais where it played a vital role in the week-long battle. In helping to stem the inexorable German armoured advance, the battalion was praised by Churchill for giving the British Expeditionary Force vital extra time to effect the crucial evacuation from Dunkirk‘s beaches.

In the spring of 1941, 3 RTR fought the panzers once again in the ill-fated Greek campaign. They fought a costly withdrawal against the Germans, losing all their tanks, but inflicting heavy casualties. Hitler was furious: the six week Greek campaign delayed Operation “Barbarossa” which allowed the Soviets time to re-group before the Germans reached Moscow.

Following their evacuation from Greece they re-formed in Egypt and fought in the Gazala battles, Operation Crusader and then in El Alamein and contributed to the subsequent defeat of the Axis forces in North Africa.

Taking part in the D-Day invasion in June 1944, 3 RTR was in the thick of all the desperate Normandy battles. They took part in the “Great Swan” to capture Amiens and Antwerp, then provided right flank protection in Operation ‘Market Garden’ and helped halt the panzers in the Ardennes. Equipped with new Comet tanks 3 RTR swept across the Rhine and four other well-defended rivers to meet the Russians on the Baltic.

Review

This book is very well informed, the author was there personally for some of it and was able to speak to those that were directly involved in other parts as well as having access to war diaries etc. The style is very readable and it is an excellent unit history for a tank regiment that was involved in all of the main campaigns in NW Europe and the Med.
