With millions of allied and enemy troops laying down their lives on the battlefields of Europe, hundreds of thousands were participating in an entirely different form of warfare, albeit equally dangerous for those involved. The War at Sea would prove to be one of the pivotal battlegrounds that would ultimately decide the outcome of the Second World War. With thousands of enemy and allied cargo ships resupplying the troops on the front line each day, it was quickly realised that theside who could sustain sea dominance would have the best chance of winning the war. In an attempt to scupper and destroy as many resupply ships as possible, the Germans had hundreds of heavy surface vessels and U-Boats patrolling the seas, with these taking the brunt of the fighting. Between them and the cargo ships stood countless allied escort vessels ready to fight to the death. These wars at sea were being fought throughout the vastness of the Atlantic Ocean. In the Pacific, however, they played only a subordinate role. Aircraft carriers, used as combat units, dominated the war here. These two films show, in fascinating detail, these monumental clashes at sea using original and unseen archive footage during the war. This footage gives an invaluable insight into the different styles of sea warfare and the varyingclasses of ships from all sides, making this DVD ideal for all naval and military fans.Special Features:Bonus Footage
