In 1793, the Duke of York was sent to Flanders in command of the British contingent of an allied force destined for the invasion of France. In June 1794, Wellesley with the 33rd regiment set sail from Cork bound for Ostend as part of an expedition bringing reinforcements for the army in Flanders. They arrived too late to participate, and joined the Duke of York as he was pulling back towards the Netherlands. On 15 September 1794, at the Battle of Boxtel, east of Breda, Wellesley, in temporary command of his brigade, had his first experience of battle. During General Abercromby's withdrawal in the face of superior French forces, the 33rd held off enemy cavalry, allowing neighbouring units to retreat safely. During the extremely harsh winter that followed, Wellesley and his regiment formed part of an allied force holding the defence line along the Waal River. The 33rd, along with the rest of the army, suffered heavy losses from attrition and illness. Wellesley's health was also affected by the damp environment.
