'Canonbury' was a British pair of long-range bombing attacks on the Skoda armaments factory at Pilsen in German-occupied Czechoslovakia (April/May 1942).
In the 'Canonbury I' first raid, on 25/26 April, the attack was entrusted to six Short Stirling heavy bombers, of which at least five bombed despite the cloud cover over the target area and one bomber being lost, and in the 'Canonbury II' second attack, on 4/5 May, five Stirling bombers attacked the target, losing one of their number.
