By 21 May the spearhead of the German military offensive in north-western France had reached the English Channel near to the port of Abbéville, closing an armoured noose around the men of the British Expeditionary Force (BEF) who found themselves trapped in a narrow salient between the French port of Boulogne and Ostende on the Belgian coast with no prospect of escape except by sea. Vice-Admiral Sir Bertram Ramsay, the hard-bitten flag officer on the Dover station, was handed the Herculean task of organising this evacuation by the Admiralty and a more inspired choice could hardly have been made. His inspirational performance in this role was matched by the heroism of those who took orders from him over the course of the next fortnight as an armada of boats ranging from the large to the ridiculously small was assembled and conveyed across the Channel to pick up the survivors of the Wehrmacht’s attack on the West.
