This talk takes as its start-point what we probably all learned at school: the Dover Patrol is synonymous with the Zeebrugge Raid, glorious bravery by the Royal Navy and a great success. It then goes back to its origins, the men who commanded it and those who served in it along with their vessels. What were they trying to do, how did they do it and were they successful? It deals with the three commanders, some Kipling poetry, a destroyer built out of two different halves, and of course the Zeebrugge Raid – that failure that became a monument to one man’s determination to secure his place in history, Roger Keyes, and the remarkable bravery of those marines and bluejackets who tried to storm the mole and the lock gates.
