Fyi Western allies troops were in the forests of Belgium, Ardennes or Battle of the bulge when the Red Army was entering Germany and discovering camps etc.

So on a timeline, the Red Army were moving much faster than the Western allies.

I think the battle of the bulge diverted enough attention from the East, to the Western flank, which made it easier for the red Army to enter.

Either way, no single effort by ANY soldier is diminished. They all fought hard and we'll, even the Nazi's.
