Normandy Beyond the Beaches

The early arrival of 12th SS Hitlerjugend, 21st Panzer and the Panzer Lehr Divisions delayed Montgomery's Anglo-Canadian capture of Caen until mid-July and prevented an early breakout into the countryside inland from Gold, Juno and Sword which was suitable for armored combat.
An early American goal was to cut the Cotentin Peninsula in two at its southern base to prevent the Germans from supplying and strengthening the deep-water port of Cherbourg, which U.S. VII Corps captured on 26 June.
Inland from Omaha and Utah, the close 'bocage' country proved advantageous to the German defenders. The Allied breakout occurred at the end of July with Bradley's Operation COBRA near St. Lo followed by the entire Allied front first moving to close the Falaise Gap before heading southward and then pivoting to the east for the capture of the Seine River crossings.
These crucial and testing weeks for the Allies are described in graphic contemporary images with full captions and authoritative text.
