By Wehrmacht,I mean all German forces;strength of the Ostheer was :2.7;strength of the Wehrmacht more than 8 million.A third? That ain't right. By 'Wehrmacht' do you mean all the armed services of Germany or just the Army (Heer)? I'm pretty sure that almost all of the front line combat strength of the Heer and Luftwaffe was committed to Barbarossa. The vast majority of the divisions not committed in 1941 were in other theatres, i.e Africa or 2nd echelon or training formations. In other words they were not front line combat capable.
The Red Army may not have been a horde of untrained men, but due to the officer purges of the late 1930s most of the best brains had been cut out of the Red Army. Many of the divisional and corps commanders facing the Germans in 1941 were either green or politically reliable officers who may not have been the best field commanders. There were some good commanders at the army level like Dimitri Lelyushenko, Boris Shaposhnikov and of course, Zhukov but most of the Red Army commanders were substandard compared to their contemparies in the Wehrmacht. The one thing in their favour was that they were on average 10 years younger and thus fitter and better able to withstand the demands of intense warfare.
Due to the staggering losses suffered in the field by the Red Army in 1941, they resorted to sending in troops with the minimal of basic training. They were also thrown piecemeal into useless offensives in late 1941 in a futile attempt to stem the march of the German Army. The Germans did suffer some significant losses but compared to the Red Army they were minimal. I no longer have my copy of 'Soviet Casualties and Combat Losses in the Twentieth Century' by Krivosheev but if you check the force losses for each side in 1941 you'll see that the Red Army and VVS (Soviet Airforce) numerically lost a lot more than the Germans did. The Soviets eventually won because they were able to replace their losses whereas the Germans were not.
I know that the divisions in the West were not apt for the war in the East,but the Ostheer had less aircraft and only as much artillery as in may 194O;there is also the point that due to Britain in the war,a lot of the German war production was committed to the air defense (88 mm guns) and the Uboats ,thus my point of a second front that became more important the following years and that was more important IMVHO than Lend-Lease.
of course the Soviets could mobilize more and FASTER their manpower (that's a reason for the German failure):in june 2.7 in september 3.4 in december 4.5 (front strength),they send more than 6 million men to the front in less than 5 months !
About the losses:I have down-loaded some excerpts from Krivosheev :Soviet losses in the 3th quarter :2.7 million ,in the 4th quarter 1.5 million (and probably to low ),but :the German losses (from Va-Banque ) 3th quarter :530000 ;4th quarter :300000 ;the ratio for the two quarters is 1-5
The weekly German losses in 1941 was 3OOOO
In 1942 the German losses were some 1100000;weekly some 20000
In 1943 the German losses were 1442654 (from an excerpt of Kursk:a statistical analysis on the net ) :weekly = 27670
Thus you see that 1941 was,relatively,worse for the Germans than 1942 and 1943 .I see a mixture of 2 possible reasons 1The German Army in 194O was not that superior (in jun e 1941 they had 3850 tanks (a lot of them PzI !) and Assault Guns for 2.7 million and in june 1944 4200 tanks and AG for 2.2 (or 2.6 )
2 .Was the Red Army in 1941 that inferior ?Krivosheev gives the following Soviet losses:1942 :6.6 million 1943:6.9 million;1944:5.7 million 1945 :2638167 !(with a weekly loss of 153893,worse than 1941 ,I don't think that one could say that the Red army was worse in 1945 than in 1941)
Loss ratio's:
1941 :1-5
1942 : 1-6
1943 :1-4.9
1944 :1-2.8(German losses were some 2 million)
for 1945 there are no reliable figures for the German losses
If one looks at the loss ratios,I think that there was less difference between the German performance in 1941,1942 and 1943;the same for the Red Army ;that's why I mentioned that the war in the East was a war of attrition between two mainly not motorised armies (if you do not object,I will develop later my argument of non motorized armies
I don't think that the Russian counter-offensives in 1941 were useless :they bought the SU the time to transfer as much as possible their industries to the east.An other point is the Russian winteroffensivewhat,IMVHO ,was a total failure and wast of manpower and war material(the Germans lost some 20000 weekly and the Russians 120000)
PS:all the loss figures are combatlosses only
