Concurrent with the siege of Bellegarde, Spanish General Antonio Ricardos attacked two French fortresses along the Tech River associated with Fort de Bellegarde, Fort les Bains at Amélie-les-Bains-Palalda 16 kilometers to the northwest and Fort de la Garde at Prats-de-Mollo-la-Preste 31 kilometers to the west.
Fort les Bains was sieged on 23 May and the garrison of 350 men surrendered on 3 June after bombardment.
The 200 man garrison of Fort de la Garde surrendered on 5 June after the fort's water supply was cut off.

The siege of Bellegarde and its garrison of 1,536 French soldiers began on 23 May. The garrison's firepower included at least 41 cannon and seven mortars.
For several weeks the Spanish siege guns pounded Fort de Bellegarde until a breach was made in the main wall.
By this time, 42 of the 50 French artillery pieces were dismounted.
Facing the prospect of an assault with his defenses compromised, Boisbrulé formally surrendered Bellegarde on 24 June.
The remaining soldiers of the garrison marched into captivity.
During the month-long siege, the French suffered losses of 30 killed, 56 wounded, and 1,450 captured.
Spanish losses are not known.
