Believing Mayne's troops to be a serious threat, Victor marched against him. The Loyal Lusitanian Legion battalion defended the Alcántara Bridge for three hours. Then, the French artillery silenced their guns and a supporting battalion of militia took to its heels. The bridge was mined, but when Mayne ordered the charges to be detonated, its heavy construction withstood the explosion. Victor's infantry then rushed the incompletely demolished span. The French hung around the area for a few days but finally withdrew. The next action was the Battle of Talavera.
