'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 four-engined 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.
