Battle of Tolosa

Battle context

The Battle of Tolosa was a subsidiary engagement fought as the Allied forces under Wellington pressed northward following their decisive victory at Vitoria days earlier. Graham's column sought to intercept the retreating Franco-Italian force under Foy before it could reach the coast and the fortress of San Sebastián, approximately 20 kilometres to the north. The arrival of Maucune's division enabled the French to absorb Graham's initial attacks and then withdraw before encirclement could be completed. The French escape preserved a portion of their force intact, complicating the subsequent Allied siege operations around San Sebastián and leaving a defended anchor on the road toward the French frontier.
