From the Daily History of World War II widget:

"1942 - French General Henri Giraud, who was captured in 1940, escaped from a castle prison at Konigstein. He lowered himself down the castle wall and jumped on board a moving train, which took him to the French border. "

Pretty cool, if I do say.

And it was the second time he escaped from the Germans, too, having been captured duringt he First World War as well!

The fellow, however, had many less than admirable qualities, as his Wikipedia bio demonstrates and overall I'm not sure he was a positive influence for the Allied war effort. As difficult as Charles De Gaulle could undoubtedly be, he seemed to recognize the need to cooperate with the allies somewhat.
