On the approach of the French force, the British outposts were withdrawn, and Ciudad Rodrigo was relieved. The headquarters of the Duke of Wellington were at that time established at Fuente Guinaldo, a village about in the rear of Ciudad Rodrigo. The 2nd battalion of the 5th Foot, guarding Wellington's headquarters, was ordered to march to the front and reinforce two brigades of Portuguese artillery and a squadron of cavalry positioned about from Ciudad Rodrigo. About to the east of that location was the village of El Bodón, which was occupied by the Third Division, under Sir Thomas Picton. The Light Division occupied the ground between the village of El Bodón and the riverÁgueda, on which its right rested. The fourth and only remaining division was in rear of Fuente Guinaldo, occupying different villages, and not brought into position. Major Henry Ridge of the 2nd/5th Foot recalled: There were two roads leading from Ciudad Rodrigo; one to Fuente Guinaldo, the most practicable for guns, was to the right of the 2nd/5th foot while the other passed through the position held by the 2nd/5th. It was some time before it became clear to the allies along which of the two roads the French would advance as the undulating ground masked the French movements. Major Ridge ordered the guns to be unlimbered and the mules harnessed, ready to move at a moment's warning and deployed the 2nd/5th along an elevated ridge, with its right protected by a deep defile. As the French cavalry approached the allied position it became clear what their objective was, and the Portugeese guns opened fire against the French columns. At this moment the Duke of Wellington arrived, and after a few minutes of reconnoitring, told Major Ridge that he approved of the arrangements he had made, and would order up a brigade of cavalry in support. However, the Duke had hardly time to move to the rear before the allies were charged by a large body of cavalry, which for a moment succeeded in capturing the guns. By well-directed running fire from the 2nd/5th, followed by a charge of bayonets, the guns were retaken, and the French repulsed. Major General Charles Colville arrived with allied reinforcements, and took command for the allied force. This force, now of about 1,500 men, maintained the post for three hours, although frequently charged by French cavalry, and exposed to heavy fire from the guns of a division of infantry in reserve. The position was eventually abandoned when the French infantry moved forward, and the allies were forced to retire. As the ground over which the allies retreated was very favourable for cavalry, the allies were forced retired in squares of regiments, and were repeatedly charged, but the French were unable to break into them. During these operations, the French pushed forward a strong body of infantry, which succeeded in cutting off the light division, but by a judicious movement of Major General Craufurd, who crossed the Agueda, that division was saved, and managed a retreat in good order.
Aftermath
The Duke of Wellington took up a position in front of Guinaldo, with the three divisions named above, from which, not being tenable, he retired on the following day and posted himself strongly behind the Cob. The French only having supplies for ten days, were obliged to fall back, and then the Anglo-Portuguese army reoccupied nearly the same ground it did before this attack. The following is a copy of the General Order issued by Wellington after the encounter:
