One of the most decisive months of World War II (1939-1945) was the 30 days between 25 July and 25 August 1944. After the success of the D-Day landings, the Allied forces found themselves bogged down in a bloody stalemate in Normandy. On 25 July General Bradley launched Operation Cobra to break the deadlock. US forces punched a hole in the German frontline and began a spectacular advance. As Patton's Third Army poured into Brittany and raced south to the Loire, the German army was threatened with encirclement. By the end of August German forces in Normandy were utterly destroyed, and the remaining German units in central and southern France were in headlong retreat to the German frontier. In this title Steve Zaloga explains how the breakout from Normandy came about.
