The dirty little secret is that Ike was prepared to commit a million Troops if that's what it took. Biased "historians" claim that the Normandy Invasion was a success because we "only" lost about 2,000 but they forget about the two month "breakout" that cost so many more lives. The first thing they teach you in infantry school is not to attempt a direct assault on an impregnable fortress. The propaganda about the "secrecy" of the D.Day landings was exaggerated. It didn't take the Germans long to beef up the defense. It boiled down to which side could afford to sustain the most casualties.
