Jehan-Aristide Paul Alain was a French organist, composer, and soldier. Born into a family of musicians, he learned the organ from his father and a host of other teachers, becoming a composer at 18, and composing until the outbreak of the Second World War 10 years later. His compositional style was influenced by the musical language of the earlier Claude Debussy, as well as his interest in music, dance and philosophy of the far east. At the outbreak of the Second World War, Alain became a dispatch rider in the Eighth Motorised Armour Division of the French Army; he took part in the Battle of Saumur, in which he was killed.

The Battle of Saumur occurred during the last stages of the Battle of France during World War II, when officer cadets from the Cavalry School at Saumur, led by superintendent Colonel Charles Michon, made a defensive stand along the Loire River at Saumur, Gennes, and Montsoreau. For two days the Cavalry School, and other assorted units which had fallen back before the German Wehrmacht advance, held off a German attack. Since the battle occurred after the message by Marshal Pétain which called for an end to fighting, the event is often considered one of the first acts of the French Resistance.
