paid off in February 1803, and Macnamara went ashore. Duel While ashore during the peace Macnamara contrived to become embroiled in a duel. While walking his Newfoundland dog in Hyde Park on 6 April 1803 he had an altercation with Colonel Robert Montgomery, when their dogs began fighting. Harsh words were exchanged, and the two parties fought a duel that evening at Chalk Farm. Both men were wounded, the colonel mortally. Macnamara was arrested on a charge of manslaughter and put on trial at the Old Bailey on 22 April. Macnamara defended himself from the charge on the grounds that he had received an affront and that it was necessary for him to challenge it in order to maintain his position as a naval officer. He summoned many of his naval friends, among whom Viscounts Hood and Nelson, Lord Hotham, Sir Hyde Parker, Sir Thomas Troubridge, Captains Martin, Towry, Lydiard, Moore and Waller; and General Churchill and Lord Minto, to testify in his defence. They supported his assertion that he was the 'reverse of quarrelsome' and the jury took ten minutes to acquit him. Napoleonic Wars Macnamara returned to service with the resumption of the wars with France and took command of the 64-gun in June 1805 for service in the North Sea. He commanded her for two years on this station before taking command of the 74-gun . Macnamara served with the Baltic Fleet under Sir Richard Goodwin Keats in the Great Belt in 1808. During this service, he took command of a squadron of gunboats and attacked a Danish brig and cutter off Nyborg. In a fierce attack, in which seven Danes were killed and thirteen wounded to one British officer killed and two seamen wounded; both Danish ships were captured. They were found to be the 18-gun Fama and the 12-gun Salorman. Macnamara was then appointed to the 74-gun in 1809. This service took him back to the North Sea and then the coast of France. While commanding a small squadron blockading Cherbourg on 24 March 1811, he chased the French frigate Amazone off Barfleur, attacking the French ship and forcing her crew to abandon and burn her. Flag rank and later life Macnamara was promoted to rear admiral on 4 June 1814, but never had an active command. He married Henrietta, the widow of Lieutenant-Colonel the Hon. George Carleton, on 26 January 1818. Rear-Admiral James Macnamara
