The 2nd/95th, as part of Brigadier-General Sir Samuel Auchmuty's force, took part in the siege and subsequent storming of Montevideo, in what is now Uruguay, and which saw Montevideo captured on 3 February 1807, after clearing the surrounding area of Spanish troops in January. The 95th subsequently saw action at Colonia against a Spanish force that had crossed from Buenos Aires; the Rifles held off the force until it could be repulsed, with the 95th gaining much praise from Auchmuty for their part in the defeat of the Spanish force. The 95th subsequently saw action in June at San Pedro where they, the 40th and light companies, fought against the Spanish force that had crossed from Buenos Aires and defeated them.
