The Siege of Astorga was an attempt by French forces to capture Astorga, Spain in a campaign of the Peninsular War. Astorga was located on the flank of the French invasion of Spain and Portugal, and was meant to be used as a headquarters during the campaign. For several weeks no attack took place, as neither side had artillery enough to fight well. Shortly after the French guns arrived, however, a hole was made in the wall and the city fell shortly thereafter.
