Sir Charles was a subaltern in 1693, when serving in the Low Countries under William III. The King went to Holland at the end of March in that year, and returned on the last day of October, when the armies went into winter quarters. Wills was in the battle of Landen and at the siege of Namur. On the 13th October, 1705, he was appointed colonel of the 30th Regiment, and sailed with it to Spain. He acted as quartermaster-general to the troops in that country, was present at Llenda, Almanza, and Saragossa, and was made prisoner in 1711 with the army under General Stanhope, but was released at the end of the war.

After the peace of 1715, being in command of the troops in the Midland district, he marched northwards to meet the rebels from Scotland, and he and General Carpenter met them at Preston. Preston was a town both Jacobite and Roman Catholic; and in it was the army of the Pretender, composed of Scottish Highlanders and Lancashire gentry and their retainers. General Carpenter, who had been marching into Scotland, turned back into Northumberland, and by forced marches had reached Durham, where he combined with General Wills, who had been sent some time before into the north to quell the many riots that preluded the insurrection.
