During World War II, between 1941 and 1945, 78 Allied Arctic convoys brought more than 4 million tons of provisions and munitions to the U.S.S.R. These deliveries played a crucial role in the Soviet war effort. More than 1,400 merchant ships and naval vessels participated in the convoys to the ports of Arkhangelsk and Murmansk in Arctic Russia, which Winston Churchill once described as “the worst journey in the world.” Besides braving frozen seas and harsh weather conditions, the sailors also had to contend with attacks from German dive bombers and U-boat torpedoes. Altogether, more than 100 convoy ships had perished by the time the war ended and more than 3,000 lives were lost. (13 PHOTOS)
