[Upon the Allied breakout from Normandy, Adolf Hitler ordered the French Atlantic and Channel coast ports to be held as “fortresses” to deny their use to the Allies and tie down enemy troops. Although the Canadian 1st Army cleared the Pas-de-Calais region of France and liberated the Channel ports of Le Havre, Dieppe, Boulogne, and Calais, the port of Dunkirk proved a much more stubborn obstacle. In early September 1944, the Anglo-Canadians completed the landward containment of the German garrison at Dunkirk. Prior to the containment, the majority of the German 226th Infantry Division had withdrawn into the Dunkirk perimeter and, along with Kriegsmarine and Army coastal artillery and other support units formed the heart of the fortress garrison. Under the command of Vizeadmiral Frisius, Fortress Dunkirk held out isolated and under siege from the landward side for the rest of the war. On 8-9 October 1944, the Czechoslovak Independent Armored Brigade Group, commanded by General Alois Liška and subordinated to the 1st Canadian Army, arrived at the Dunkirk perimeter and took over from the British as the operational controlling element of the containment forces for the rest of the war. On 5 April 1945, Frisius launched Operation “Blücher,” a raid in force against the enemy positions around his perimeter. The raid so surprised the British command that it blew the bridges over the canals near the town. Although the Allies counterattacked under heavy air cover, they failed to dislodge the Germans from their newly established positions. On 9 May 1945—the formal capitulation of Germany—Vizeadmiral Frisius surrendered Fortress Dunkirk to General Liška at Wormhoudt.]
