In January 1944, a state of siege was declared in Haute-Savoie. Anyone found carrying arms or assisting the Maquis was subject to immediate court martial and execution. Hunted by the Vichy police and badly supplied, most of the maquisards gathered on the Glières Plateau to set up their base of operations. Soon after, 100 French communist resistants and about 50 Spanish lumberjacks joined forces with them in taking refuge and getting weapons. From 13 February, the 450 maquisards, under the command of officers from the 27e bataillon de chasseurs alpins, were besieged by 2,000 French militia and police. Although they suffered from starvation and freezing conditions, they collected three parachute drops consisting of about 300 containers packed with explosives and small arms, including Sten sub-machine guns, Lee–Enfield rifles, Brenlight machine guns and Mills bombs. On the night of 9/10 March, the commander-in-chief, Lt. Tom Morel was killed in a skirmish with the Vichy forces. On 12 March, after the largest Allied parachute drop, the Germans started to bomb the area with ground attack aircraft. The Milice staged several attacks which failed. On 23 March, three battalions from the German 157th Reserve Division and two Order Police battalions, composed of more than 4,000 men, with heavy machine guns, 80 mm mortars, 75 mm mountain guns, 150 mm howitzers and armoured cars, concentrated in Haute-Savoie.
Retreat
On 26 March 1944, after another air raid and shelling, the Germans took the offensive. They split their attacking parties into three groups with an objective for each group. Reconnaissance was carried out by ski patrols dressed in white camouflage. One of the patrols with a Gebirgsjäger platoon, made an attack on the main exit of the plateau and captured an advanced post in the rear. Sustaining the attack from about fifty German soldiers, eighteen maquisards fought and resisted into the night but were outnumbered and overwhelmed, though most of them escaped under cover of darkness. At ten o'clock, Captain Anjot ordered the Glières battalion to retreat. In the days that followed, he and almost all his officers as well as 120 maquisards were found dead. They had been killed in battle or, if taken prisoner, had been tortured, shot or deported. The Germans considered the maquisards terrorists. The region of Savoie had suffered badly, but the defeat was turned into a propaganda victory and gave a boost to the French Resistance in the spring of 1944.
