Squadron Flag-Ship
Three month later, during a firing practice exercise, she hit a magnetic mine and was put out of action for three years. Re-commissioned from Davenport where she had been sent for repairs and upgrading, Belfast became the flag-ship of the 10th Cruiser Squadron, escorting Arctic convoys to the Soviet Union.
Later that year, during the Battle of the North Cape, Belfast helped in the sinking of the German battle-cruiser Scharnhorst, the last battle between the British and German’s heavily armed and armoured battleships.
