It was only by some masterly maneuvering and some stiff fighting at Venta de Pozo, on the Carrion, and on the Huebra, that Wellington drew off his army to Ciudad Rodrigo.

During the retreat the British suffered very severely, and the discipline of the army became greatly impaired, so much so that Lord Wellington issued a general order rebuking the army, saying that "discipline had deteriorated during the campaign in a greater degree than he had ever witnessed or read of in any army, and this without any unusual privation or hardship, or any long marches."

The number of stragglers may be imagined by the fact that the loss of the allied army was upwards of nine thousand, of whom not more than two thousand were killed and wounded at Burgos, and in the combats during the retreat. This number includes the Spanish as well as the Anglo-Portuguese loss.

It was the beginning of December when the allied army reached their winter quarters around Ciudad Rodrigo. It was fortunate that the season of the year, and the necessity which the French had to refill their magazines, and collect food, gave breathing time and rest to the British. Although strengthened by his junction with Hill, and by the arrival of reinforcements from the coast, Wellington was not in a position to have made a stand against such a force as the French could have brought against him.
