The position of Cadiz, on a narrow peninsular, made its long term defence viable provided it cound be supplied from the sea. The initial garrison of 2,400 was reinforced by 13,000 Spaniards and then by three British and two Portugese battalions bringing the total strength up to over 20,000. Over the duration of the siege it involved some 60,000 French troops who suffered a constant trickle of casualties due to sickness, sorties and guerrilla raids. Many troops were also involved in protecting supply routes to the investing force. After the French defeat at Salamanca Soult withdrew his troops.
