Gas- and diesel-powered AFVs in the Allied armed forces
Hello,
At first quotation from the GOC 4th Canadian Armoured Division Maj.-Gen. George Kitching's memoirs: Quote:
▪ M3A1 Stuart (or Stuart Mk. IV) powered by the Guiberson T-1020-4 Diesel engine ▪ M4A2 Sherman powered by GM 6046 diesel engine ▪ M10 tank destroyers and their Achilles versions powered by GM 6046 diesel engines Did I miss any model? Was there a possibility for the GOC to select the tanks for his division? Best regards C. Last edited by Crewman; 21-04-05 at 19:24. |

They may have been obsolete by the time the Allies were in Normandy, but there were diesel versions of the Matilda (Leyland diesels) and Valentine (Val II and Val III with AEC diesel, and Val V with GM 6-71), as well diesel versions of the Lee/Grant with GM 6-71.

Tony,
Thanks for additional info! But what about the commander's right to choose for his unit the tanks with optimal powerplant? I have never met an information that somebody in the ETO chose the tanks for his unit. I understand that General Dempsey's wishes for Maj.-Gen. Kitching were pure theory...? Best regards C. |

In fact once ignited diesel has more heat output and is more difficult to extinguish, the main reason for the petrol fire myth is poor design in ammunition stowage. The initiator is shell propellant and far more dangerous than petrol or diesel oil, it really makes no difference what the fuel is when just one case is ruptured and the resulting virtual aerosol of propellent charge is ignited. German tanks did not catch fire readily at all and almost entirely owing to good design and therefore protection of the main gun ammunition. So much so that the average lay-man here at least has a belief that WWII German tanks were all diesel powered because when hit immediate fires didn't occur. I think Hanno can add something to this, especially the Sherman mods that saw appliqué armour placed in the vulnerable places and IIRC some research that suggests American crewed Shermans went on fire at a rate 5 times greater pro rata than equivalent British operated vehicles because of the US practice of sneaking in extra main gun rounds wherever they could be tucked away.

Panther vs Shermamn
The German Panther tank was just as prone to catching fire, if not more so, than the Sherman. Its ammo storage was similar to the Sherman with the rounds carried in the sponsons. Its petrol tanks were in vulnerable positions and would catch fire if the tank was hit in the engine compartment. There was also a problem with the hydraulic fluid in the steering system and in the power traverse.
In a report on the situation of the German armoured forces in Normandy, given to Hitler on the 28th of June 1944, the General Inspector of Panzer Troops, General Guderian wrote; “…,but the Panther catches fire very quickly and in an astonishing way.” Herbert Walther, who was the ordnance officer in the 2nd Bn of the 12th SS Pz Regt, wrote in his history of the 12th SS Panzer Division; “The fact that the "Panther" could catch fire quickly was attributed to the hydraulic fluid in the steering system. A few days later a "Panther" caught fire immediately from a hit on its bow plate that did not break through the armor at all. Later, when an experienced English tank sergeant was taken prisoner, he made a show of turning away before striking a match. When asked why, he said with a wink of his eye that it was better to look all around in case a "Panther" was in the vicinity, as it would burn and explode immediately.” |

Well, the only one small problem was to hit and pierce this Panther. On August 8th, 1944, a mile east of Saint-Aignan-de-Cramesnil small elements of the "Kampfgruppe Waldmüller" smashed three Polish armoured regiments killing 36 tanks without any loss. Next day the "Kampfgruppe Wünsche" smashed the BCR and Algonquin Regts. also without any loss and killing 47 tanks. Etc., etc.,...

If you are interested in which units actualy used the Diesel engined Sherman 111 (M4A2), can I recommend Peter Browns article in 'Tracklink' number 41 (contact Tank Museum for copy). To summarize, Peter notes that the Sherman 111 was principaly restricted to the independaent armoured brigades. In June 1944 8th AB had 95, 27th AB 126, 2nd CdnAB 95, and 150 were with the Armoured Replacement Group. Total 466. The most commom model in service was the Sherman V (M4A4) with 940 with units or ARG (not including Fireflies on same chassis). After this date unfortunately Shermans were only identified by gun type in the offical records. |

Neil, thank you very much!
That is the info I looked for, among others. The info for the hobbyists, not necessarily easy to find in the Generals or classic historians' books. Are there any memoirs of the tank crews using diesel Shermans in the ETO and theirs opinions about possible advantage of the diesels over gas-powered Shermans? Best regards C.

Post-war
My interest in wartime diesels is because the General Motors Limited Southampton Plant was possibly going to assemble 6-71 diesels for the Royal Navy from 1941 but it was bombed 30 November 1940. However this is a quote from my text, based on GENERAL MOTORS WORLS April-May 1948, concerning the imediate post-war Southampton Plant activities:

Re: Panther vs Shermamn

Owing to an exhaust leak, shutting the engine off as "normal" with the ignition would regularly cause a huge backfire since the engine momentum will fill the system with a quantity of ignitable fuel/air mixture, with a very hot exhaust system and probably some glowing carbon deposits therein, a backfire will have flame pass through at least one cylinder to the inlet manifoldand cause a carb fire. The received wisdon was to stall it at idle and then switch the ignition off. The design of the Stalwart system does this also but the nature of the sealed carb and intake with oil bath air cleaners seems to preclude carb fires; plus with only 8 pots the chances of a cylinder resting on the valve overlap period is reduced. I have had it do a very passable imitation of a 25pdr some considerable time after shut down, having clambered out of the cab and walked some distance away from the vehicle. In sensitive locations I also choose to stall it at idle in a high gear. Its a well known trait amongst operators. R. |

The first encounter between a Panther and a Sherman occurred in Italy on the 24th of May 1944. A Sherman tank of the British Columbia Dragoons, commanded by Lt. Nigel Taylor, met a Panther near the Melfa River. His gunner Tpr. Cecil Shears fired two quick shots from their 75mm gun at a range of about 1000 yards and the Panther was finished. In the Panthers first actions in Normandy on the 8th and 9th of June near Bretteville-l’Orgueilleuse and Norry-en Bessin, the Panther came off second best. The 12th SS Pz Regt Lost 12 Panthers destroyed, with another three or four damaged, but could only claim one Sherman destroyed. In a three day period (20 July -22 July) Sherman tanks commanded by Maj. S.V. Radley-Walters destroyed 22 Panthers along the Verrieres Ridge. This is confirmed in the records of 1st SS Panzer Division “Leibstandarte” which had 46 Combat ready Panthers on the 17th of July. This dropped to 24 Combat Ready Panthers on the 22nd of July. The Panther was at its best when it was in a defensive hull down position where it could pick off allied tanks at longer ranges. However, the Germans had an obsession with counter-attacks. They persistently sent their Panthers out onto the attack where combat occurred at shorter ranges, resulting in high losses. |
