While employed Everard led the forlorn hope at the storming of Montevideo 3 Feb. 1807, when twenty-two out of thirty-two men with him were killed or wounded. For this service Everard received a sword of honour from Lloyd's Patriotic Fund and the Freedom of the City of Dublin. He was also promoted, 23 April 1807, to a company in the 2nd battalion 14th foot, with which he served at the Battle of Corunna and in the Walcheren Campaign. During the latter he was thanked in general orders for his conduct at the siege of Flushing, 12 Aug. 1809, when the flank companies of the 14th, one of which he commanded, supported by the rest of the battalion, in conjunction with some of the German legion, stormed one of the enemy's batteries and effected a lodgment within musket-shot of the walls. He was subsequently transferred to the 1st battalion of his regiment in India, and commanded it at the siege of Hattrass in 1817. He commanded a flank battalion in the operations against the Pindarrees in 1818–19, was made regimental major 10 July 1821, and commanded it at the storming of Bhurtpore 29 December 1825, when the 14th headed one of the columns of assault, and unsupported cleared the breach after the premature explosion of a mine, and effected a junction with the other column led by the 59th foot, the steadiness and discipline of these two regiments, to quote the words of Lord Combermere, "deciding the fate of the day".
