ok, only belatedly during 1944-45 were the US Army's black infantry replacement platoons in ETO assigned to white inf coys amongst 1st & 7th Armies, to replace losses sustained during the Battle of the Bulge in the aftermath of which trained white combat troops were running low. WI say such racial integration had been compelled to occur at an earlier stage ? Perhaps, in the aftermath of an even worse outcome for the green American troops in Tunisia after Kasserine Pass in 1943, or maybe more casulaties sustained during the bocage fighting in Normandy ? In PTO, there was also some ad hoc de facto integration of black & white combat troops, as occurred on Bougainville 1944 when units of the 93rd BLOODY HAND Div & 24th inf Regt were incorporated piecemeal sometimes with the white AMERICAL & 37th BUCKEYE Divs, or in italy by 1945 when the 92nd BUFFALO Div had 2 of its depleted black inf regts withdrawn to be replaced by the Nissei of the 442nd RCT & the white 473rd Inf regt. WI such combat integration had occurred more systematically & earlier in the US armed forces during WWII ?
