, first earl of Cadogan, the son of Henry Cadogan, a counsellor at law, by Bridget, daughter to sir Hardress Waller, knt. was educated to a military life, and in 1701 was made quarter-master-general of the army. In 1703 he was constituted colonel of the second regiment of horse, and on August 25, 1704, brigadiergeneral, having that year behaved with great gallantry at the attack of Schellenberg, and the battle of Hochstet. In June 1705 he was elected member of parliament for Woodstock; and on July 18th of the same year, at the forcing of the French lines near Tirlemont, he behaved with remarkable bravery at the head of his regiment, xvhich first attacking the enemy had such success, that they defeated four squadrons of Bavarian guards, drove them through two battalions of their foot, and took four standards. He was also in the battle of Ramilies, fought on May 12, 1706; after which the duke of Marlborough sent from his camp at Meerlebeck, on June 3, brigadier Cadogan, with six squadrons of horse, and his letter to the governor of Antwerp, to invite him and the garrison to the obedience of king Charles III. and having reported to his grace that ten battalions were in the city and castle of Antwerp, who seemed inclined to surrender on honourable terms, the duke sent him authority to treat with them. And after some conferences, they complied, and the garrison, consisting of six French and six Spanish regiments, were allowed to march out in three days, and be conducted to Quesnoy. But of the Walloon regiment, consisting of 600 men each, only 372 men marched out; the rest entering into the service of king Charles, except some few who were not in condition to serve, and returned to their respective dwellings. Afterwards, towards the close of the campaign that year, he was taken prisoner when on a foraging party, and was carried into Tournay, but he remained there only three days, the duke of Vendosme sending him, on August 19, to the duke of Marl bo rough’s camp, upon his parole and five days after he was exchanged for the baron Palavicini, a major-general in the French service, taken at the battle of Ramilies. On Jan. 1, 1706-7, he was promoted to the rank of major-general of her majesty’s forces. On Mr. Stepney’s decease in 1707, he succeeded him as minister plenipotentiary in the government of the Spanish Netherlands. And he soon after, in conference, brought to a conclusion the negotiation for the speedy exchange of prisoners; and, having shared in the most difficult enterprizes throughout the war, was constituted a lieutenant-general on January 10, 1708-9.
