The Virée de Galerne campaign and the battle of Le Mans
On December 10, 1793, the Catholic and Royal army took over Le Mans. The Republican troops retook the town on December 12 and 13. 20,000 to 30,000 Republican soldiers faced 30,000 to 60,000 Vendeans, of whom 10,000 to 20,000 were combatants. Most of the Vendean army fled the town in a forced march in the direction of Laval. Following the fighting, there were reprisals on prisoners and fugitives - the sick, injured, elderly, women and children - at Le Mans and in its surroundings. 2,000 to 5,000 Vendeans were killed in the battle, with barely a hundred dead among the Republican forces. This great Vendean army, mainly composed of the inhabitants of Angers, was already subject to high mortality, even when not fighting, due to an epidemic of dysentry accompanied by a putrid fever: "the Brigantine sickness".
The battle of Le Mans is an important episode in the "Virée de Galerne" during the first Vendée war. The "galerne" is the wind from the north-west, and here and for the Vendeans signifying the land to the north of the Loire River. The Virée de Galerne began on October 18, 1793, following the defeat at Cholet. It ended with the annihilation by Kléber's troops of the Catholic and Royal army led by the 21 year old general Henri de la Rochejacquelin at Savenay, on December 23, 1793.
