Jones, Tim Kilvert. "Bloody Normandy: The German Controversy"
Divergence: 1944 CE
What if: Rommel was not on leave on June 6, 1944, and German panzer divisions in Normandy were deployed differently and thrown into battle at once.
Summary: Americans are annihilated at Omaha Beach, but the Allies still overcome German defenses.
Comments: On a similar theme but with different results, compare with Tsouras's Disaster at D-Day.
