Alexander Campbell, Brevet-Major in the army, and a Captain in the 21st regiment, stood indicted for the “wilful and felonious murder” of Alexander Boyd, a captain in the said regiment, by shooting him, the said Alexander Boyd, with a pistol bullet. To support this indictment, the following witnesses were produced:— George Adams, who stated, that he had been assistant surgeon in the 21st Regiment, since April twelvemonths. He knew Major Campbell and Captain Boyd. In the year 1807 they were quartered in the barracks, in the county of Armagh side of Newry. On the 23rd of the said month, Captain Boyd died of a wound he received by a pistol bullet, which penetrated the extremity of the four false ribs, and lodged in the cavity of the belly. On that day the regiment was inspected by General Kerr; and, after the inspection, the General and officers messed together. About eight o’clock all the officers left the mess, except Major Campbell, Captain Boyd, witness, and a Lieutenant Hall. A conversation then commenced by Major Campbell stating, that General Kerr corrected him, that day, about a particular mode of giving a word of command, when he conceived he gave it right. He mentioned how he gave it, and how the General had corrected him. Captain Boyd remarked, that neither was correct according to Dundas, which was the King’s order. (This observation, witness stated, was made in the usual mode of conversation.) Major Campbell said, “it might not be according to the King’s order, but still he conceived it was not incorrect.” Captain Boyd still insisted it was not correct, according to the King’s order. They argued this some time, till Captain Boyd said,—he knew it as well as any man. Major Campbell replied,—he doubted that much. Captain Boyd at length said,—he knew it better than he, let him take that as he liked. Major Campbell then got up and said, “Then, Captain Boyd, do you say that I am wrong?” Captain Boyd replied, “I do. I know I am right by the King’s orders.” Major Campbell then quitted the room. Captain Boyd remained after him for some time. He left the room before the witness or Lieutenant Hall; but no observation was made on his going, more than on that of any other gentleman that had dined there. The witness and Lieutenant Hall went out together in a short time after. They went to a second mess-room, and there Captain Boyd came and spoke to them. (The conversation was not admitted in evidence, as Major Campbell was not present at it.) They then went out together, and the witness left Captain Boyd at Lieutenant Dewar’s. In about twenty minutes after he was called upon to visit Captain Boyd. He went, and found him on a chair vomiting. He examined his wound, and found it a very dangerous one. He survived it but eighteen hours. He stayed with him till he died, during which time he got gradually worse.
