the cRAF did their part too though they are usually spoken poorly of by the soldiers during this operation. clouds prevented soldiers from seeing the raf in action and short range fighters had a limited time over dunkirk compared with loiter time for the luftwaffe.
good thinng hitler listened to goering instead of sneding in the panzers.
a lot of frencjmaen were qalso saved during the evacuation. IIRC lightower of titanic fame used his boat in the evacuation.
And, yes, Commander Lightoller, by that time a retired officer of the Royal Navy (he was twice decorated during the First War) took his motor yacht, the Sundowner across during the evacuation and brought about 130 men back to England. The vessel is now moored at the Ramsgate Maritime Museum in England, as an example of one of the larger of the 'little ships'. She stayed in service as a patrol vessel for the rest of the war.
