Correct ! La Grande Asperge indeed -- Wiki tells us that he acquired the nickname as a lad, attending the St. Cyr military academy (France's Sandhurst): "because of his height, tall forehead, and nose".Is La Grande Asperge General Charles de Gaulle? No idea where it came from except possible his height (certainly for a Frenchman of that era).
A vous. Monsieur, de poser la prochaine question.
