May 1635 CE
The open war with Spain starts with a promising victory for the French at the Belgian village of Les Avins on May 20, 1635, in what is at this time the bishopric of Liège.
The Spanish army, inferior in numbers, is surrounded and completely defeated in just a few hours.
Some five thousand Spanish are killed or wounded, fifteen hundred captured and the rest scattered.
It is the first serious engagement for the French, which had entered the war only three months before.
