By Moonlight is a book written by Peter Churchill, DSO, Croix de Guerre, published in 1958.
Churchill worked with the Maquis des Glières during his wartime activities in the French section of the Special Operations Executive.
Their leader, Tom Morel, whittled down his numbers to 450 picked men of whom 50 were Spaniards, and made them all take an oath "Vivre libre ou mourir" (live free or die) to fight for their freedom.
His motto is carved on the stone monument inside the Morette Cemetery on the Annecy-Thones road where 112 men, including their commanding officer, lie as a constant reminder of their epic battle in March 1944.
Surrounded by 10,000 soldiers of a German Mountain Division armed with 88-millimetre guns and three-inch mortars, and battered in advance by two squadrons of Stuka Dive Bombers, this handful of men fought against 22 times their number.
