Tedder contributed to the German defeat in North Africa and the success of Allied landings in Sicily and Italy (1943) by cooperating with other Allied forces, interdicting enemy supply lines, and giving tactical support to Allied ground troops.A ppointed Eisenhower’s deputy in early 1944 and responsible for coordinating all Allied air operations in western Europe, Tedder repeated his earlier successes by sealing off the Normandy beaches from the air and keeping German reinforcements from reaching the Allied beachhead. His bombing of the German transportation network significantly sped the Allied advance during the final months of World War II.
