Walcheren was invaded by an army of nearly 40,000 men in 15 brigades. This was an attempt to destroy a French fleet and to turn Napoleon's attention from Austria to them. They landed on 30 July. On 1 August, with the 85th Regiment Of Foot, they pursued their opponents to the walls of Flushing, which fell after the siege on 15 August. The regiment left in December to go to Deal.
