In September, Suchet launched an invasion of the province of Valencia. He besieged the castle of Sagunto and defeated Blake's relief attempt. The Spanish defenders capitulated on 25 October. Suchet trapped Blake's entire army of 28,044 men in the city of Valencia on 26 December and forced it to surrender on 9 January 1812 after a brief siege. Blake lost 20,281 men dead or captured. Suchet advanced south, capturing the port town of Dénia. The redeployment of a substantial part of his troops for the invasion of Russia ground Suchet's operations to a halt. The victorious Marshal had established a secure base in Aragon and was ennobled by Napoleon as the Duke of Albufera, after a lagoon south of Valencia.
