Commander James Campbell Clouston's pivotal role in the evacuation of some 167, 000 British troops is beyond dispute. His actions are reviewed in this book, including the fraught situation he got caught up in, which was to cost him his life. He was found to be in the way for two different reasons. First, the Admiralty had suddenly banned ships from going anywhere near Dunkirk during daylight hours, and no ships meant Clouston would have had nothing to do all day.
How was he supposed to proceed? He wasn't. He was ferreted back to England. The official statement that he'd gone back for a meal, a shower and a rest is nonsense.
