When nineteen he enlisted for the "Mexican War" and was elected First Lieutenant of Captain Beard's company, in Colonel Marshall's regiment of cavalry. He served in Mexico for eighteen months, but did not, he used to say, see much of "war" during that time. He was, however, at the battle of Buena Vista, in which fight Colonel Marshall's regiment was hotly engaged, and his company, which was ably led, suffered severely. Soon after his return home he married Miss Bruce, of Lexington, a sweet and lovely lady, who, almost from the day of her wedding, was a confirmed and patient invalid and sufferer. Immediately after his marriage, he entered energetically into business--was industrious, enterprising and prosperous, and at the breaking out of the war in 1861, he was conducting in Lexington two successful manufactories. Every speculation and business enterprise in which he engaged succeeded, and he had acquired a very handsome property. This he left, when he went South, to the mercy of his enemies, making no provision whatever for its protection, and apparently caring not at all what became of it. As he left some debts unsettled, his loyal creditors soon disposed of it with the aid of the catch-rebel attachment law. When quite a young man he had two or three personal difficulties in Lexington, in one of which he was severely wounded. To those who recollect the tone of society in Kentucky at that day, it will be no matter of astonishment to learn that a young man of spirit became engaged in such affairs. His antagonists, however, became, subsequently, his warm friends. The stigmas upon General Morgan's social standing, so frequent in the Northern press, need not be noticed. Their falsity was always well known in Kentucky and the South.
