Before World War II, the Belgian port city of Antwerp was one of the world’s great ports, ranking with those of Hamburg, Rotterdam, and New York. Antwerp is located some 55 miles up the Scheldt (Schelde) Estuary from the North Sea. Five hundred yards wide at its location on the estuary, the port’s minimum depth along its quays is 27 feet, deep enough to handle the largest ships in the world—especially when it comes to maneuvering such vessels into place along the quays.
The port’s capacity is prodigious; in 1944 alone there were nearly 26 miles of quays that were serviced by 600 hydraulic and electric cranes, in addition to numerous floating cranes, loading bridges, and floating grain elevators. Extensive storage accommodations around the port and excellent road and rail clearance facilities were available. And on September 4, 1944, although in German hands, the port’s facilities were virtually undamaged and fully functioning.
For the Allies, after their breakout from Normandy, it was vitally important that Antwerp be captured and placed in operation as soon as possible. If the war in northwestern Europe was to be concluded expeditiously, the port would play a key role in supplying both British and American army groups.
