The destroyer "L'Indomptable", launched in 1934, was the first to carry the insignia of the French Foreign Legion. The ship's first commander asked Général Paul-Frédéric Rollet to have the Legion as the ship's patron and guardian. The fanion of "L'Indomptable" was green and red, with the cannons depicted carrying the words "Magenta", "Camerone", "Tuyen Quang", and "Laffaux" (after the battles of Magenta, Camarón, Tuyên Quang and the Aisne – four engagements in which the Legion distinguished itself), and displaying the Legion's grenade as an insignia. The nuclear ballistic missile submarine "Indomptable" launched in 1974 continued the association.
