June 4, 1944, 18:30, southern England. Liaison officers boarded twenty-two French buildings. Locked up with the commanders, they hand them a large sealed envelope. From the start of the English, the "pashas" discover their mission in the "Neptune" operation (code name for the Allied troops landed in Normandy).Crews are combined. The men discover they are the first to contribute to the French landing. Many of these sailors from France who will participate in the largest operation ship of all time joined de Gaulle in Britain. However some, starting with their chief Admiral Jaujard, are more reticent with regard to the general.This is the story of these ships and the men who form the core of the book. Among them, Querville with his submarine Juno who landed in Norway a commando responsible for blowing up a heavy water plant; or Levasseur with Aconite which sank two U-Boote in twelve hours.The participation of French sailors is rarely, if ever, mentioned when famous anniversaries of the Normandy landings. There is only time to repair the injustice done to these men, their buildings and the Navy.
