Lionel de Marmier

Lionel Alexandre Pierre de Marmier was a World War I flying ace credited with six aerial victories in WWI. He scored 2 or 3 more victories in WWII.

When the new SPAD XII came out, it was distributed one per French squadron. The "cannon Spad" for their unit was shared between Marmier and his friend Fernand Henri Chavannes; it even bore the shared marking of an 'M' entwined with a 'C'.

Between the wars, he served with the Spanish Republican Air Force from 1936 to 1937.

At the start of World War II, Marmier returned to duty in and shot down at least two German planes in June 1940, while he was flying a Caudron C.714 with the Polish pilots of GC 1/145 'Varsovie'. After the French surrender, he joined the Free French Air Force and served in it until his disappearance in 1944.
