Ship’s Log (No. 093) – 29 May 1940
The Deadliest Day of Operation Dynamo
On this day in 1940, the Dunkirk evacuation suffered its heaviest losses as German aircraft and E-boats relentlessly attacked Allied shipping attempting to evacuate troops from Dunkirk.
Throughout the day, the Royal Navy and supporting vessels came under sustained assault in the English Channel and off the beaches of Dunkirk. The destroyers HMS Wakeful, HMS Grafton, and HMS Gr***de were all lost during the evacuation effort, alongside passenger steamers, minesweepers, and numerous smaller craft including Mona's Queen.
More than 1,000 Allied troops and sailors were killed during the attacks, making 29 May the deadliest single day of Operation Dynamo. Despite the heavy losses, the evacuation continued, with Royal Navy crews and civilian mariners repeatedly returning to the beaches under fire to rescue stranded soldiers.
The sacrifice of the ships and crews at Dunkirk played a critical role in preserving the British Army and enabling the wider evacuation effort that would ultimately save more than 338,000 Allied troops.
