Operation Cobra

Battle context

Operation Cobra was launched by the First United States Army under Lieutenant General Omar Bradley seven weeks after the D-Day landings as part of the broader Normandy campaign. Its intent was to exploit the pressure exerted by British and Canadian attacks around Caen in Operation Goodwood, using that distraction to rupture German defensive lines that had been containing Allied forces in the bocage country. After a slow start, the offensive gathered momentum as German resistance collapsed, with scattered remnants of broken units fighting to reach the Seine rather than holding ground. The German response was rendered ineffectual largely due to the simultaneous pressure of Operation Bluecoat, which denied German commanders the resources needed to stabilize the front. Cobra opened a corridor that allowed the First Army to advance toward Brittany and roll up German flanks. Together with concurrent offensives by the British Second Army and the Canadian First Army, Operation Cobra was decisive in securing the Allied victory in the Normandy campaign, ending the attritional stalemate that had defined the weeks following D-Day.
