The Breskens Pocket was a pocket of fortified German resistance against the Canadian First Army in the Battle of the Scheldt during the Second World War. It was chiefly situated on the southern shore of the Scheldt estuary in the southern Netherlands, near the Belgian border. It was named after the town of Breskens, which was later freed from German occupation during Operation Switchback.[2]
An intelligence summary by 1st Canadian Army in the immediate wake of the battle, referred to the 64th Infantry Division as "the best infantry division we have met." The Germans had been well supported by numerous heavy guns of the Atlantic Wall and the terrain had been atrocious. Canadian official history noted, Belgian military manuals described the local polder as "generalement impropre aux operations militaires". The Canadians suffered 2,077 casualties while the Germans had suffered 12,707 soldiers killed, wounded, missing or captured.[1] When Operation Switchback ended, British general Bernard Montgomery bestowed the nickname "Water Rats" on the 3rd Canadian Infantry Division, a play on the Desert Rats title the 7th Armoured Division had earned during the Western Desert Campaign. Canadian General Harry Crerar reportedly hated the term, though it was meant as a tribute to their success in amphibious operations in Normandy and the Scheldt.
