DUNKIRK
18 Blenheims bombed, no losses.
This day saw the end of the evacuation from Dunkirk. 2 Group's Blenheims had flown on all but 3 days - days when weather conditions had been bad - since the opening of the German offensive; they had also flown 1 night operation. A total of 956 sorties had been flown and 57 aircraft lost. This was a loss rate of 6.3 percent, or the equivalent of 4 complete squadrons from the 9 squadrons in 2 Group which were operational during most of this period.
The Blenheims were given 1 day's rest before resuming operations, this time in support of the French Army and the few remaining British units further south in France.
