I recently acquired a current copy of the magazine Military History and I found in it an account of the Battle of Trafalgar. Included was an extract from a letter written by Jean-Jacques Magendie who was captain of Bucentaure, Admiral Villeneuve's flagship. I found this part of it particularly interesting:
".....I went on deck again at the moment when Admiral Villeneuve was constrained to strike [surrender], to prevent the further slaughter of brave men without the power of retaliating, which was done after three and a quarter hours of the most furious action, nearly always at pistol range. The relics of the eagle were thrown into the sea, as were all the signals." (My italics)
Does this mean that French flagships carried eagles, the way that French infantry regiments did? If so, did we ever capture any?
