#OnThisDay 1940 Operation Dynamo, the evacuation of British troops from Dunkirk ended. 2 Royal Ulster Rifles had the unenviable task of holding the perimeter defence while the evacuation took place. They’d lost nearly 200 men, 34 killed, 70 wounded with 70 missing or captured by the enemy. They managed to hold out the perimeter until they got off the beach on June 1st. Roughly 340,000 troops got off the beach.
