Operation Dynamo
HMS Sabre was conspicuous in the evacuation of British and French soldiers from the beaches of beaches at Malo-Les-Bains and the harbour mole during the Dunkirk evacuation. During nine days and nights of the evacuation, despite being damaged in an air attack, Sabre made ten round trips to Dunkirk. An example of her activity at this time:
In the early hours of 28 May, three ships boats from HMS Sabre picked up 100 men in two hours, from the beaches at Malo-Les-Bains to the east of the harbour mole. Then it was full speed to Dover with a turnaround of only 58 minutes, and the ship was back again at the Dunkirk harbour mole at 11.00am, where they loaded a further 800 men. Departing at 12.30pm, by now the ships weight had increased considerably, lowering her propeller draft. This meant because of the falling tide and a defective echo sounder, Lieutenant-Commander Dean had to slowly edge her passage through the shallows. She arrived back in Dover at 6.20pm. Refuelled, she was back to the Dunkirk mole at 10.30pm, the third trip of the day. This time, the ship stayed for only 35 minutes picking up another 500 troops.
Finally on Tuesday 4 June just after two in the afternoon the Admiralty announced the end of Operation Dynamo. All together an armada of over 860 ships including 39 destroyers had taken part in the evacuation of troops from the beaches and harbour. The Admiralty calculated the total British and Allied troops landed in England amounted to 338,226 troops rescued.
HMS Sabre had made more round trips than most and brought back to Dover a total of 5,765 soldiers – amongst the highest number for any individual ship. Lieutenant Commander Dean was awarded a Distinguished Service Order on 6 June. Archdale, Sabre's midshipman, was mentioned in despatches.
