Col. Alfred M. Wood. Alfred M. Wood, ex-mayor of Brooklyn and Colonel in command of the Fourteenth Regiment during the war, died at his home, in Queens, L.I., yesterday morning, from the effects of a fall in New-York City about a month ago. He was sixty-eight years old. Col. Wood was born in Hempstead, L.I., in 1827. He was educated in the village school. He secured a situation in Brook- lyn dry goods store, and by hard work ad- vanced himself until he became proprietor of the business, which he conducted until 1854. Col. Wood's first service in the militia was with the Brooklyn City Guard. When this organization was merged with others into the Fourteenth Regiment, he got a Major's commission, and later became Colonel. He was elected President of the Brooklyn Board of Aldermen on the Democratic tick- et in 1858. At the outbreak of the civil war the Fourteenth Regiment was anxious to go im- mediately to the front. Gov. Morgan, how- ever, refused permission. Col. Wood tele- graphed to President Lincoln that the regi- ment was ready and was only awaiting or- ders. The orders soon came, and, in spite of the disapproval of the Governor, the regi- ment went at once into service. In the bat- tle of Bull Run Col. Wood's horse was shot under him, and he himself received a severe wound in the breast. The bullet passed through a pack of visiting cards, which he afterward preserved as a memento. He was captured during the confusion of re- treat and sent to the Confederate hospital in Richmond. While there he had the offer of a Brigadier General's commission if he would join the Confederate Army, but he promptly refused. Later he also refused a similar commission offered by President Lincoln. Col. Wood was confined in Libby Prison until his wound had healed somewhat. While there he was twice selected by lot to die, in retaliation for the threatened execution of Confederate prisoners by the Federal civil authorities, but no such retaliation proved necessary. He was finally exchanged, and, returning from the war in ill health, in the year 1863, he was appointed Collector of Internal Revenue for the First District of New-York. In the Fall of 1864 he was elected Mayor of Brooklyn by a handsome majority. After his term had expired, he lived in retire- ment until 1878, when he was appointed United States Consul to Castel-a-Mare, Italy, where he remained until last year. While in New-York, four weeks ago, he fell on the sidewalk as he was about to go up the stairs to Brooklyn Bridge. He was picked up unconscious and taken to a private hospital. The next day he had re- covered sufficiently to go home. He ap- peared to get well, but two weeks ago he began to complain of pains in the spine. In spite of the efforts of physicians, he gradu- ally became worse. He lapsed into uncon- sciousness about a week ago and remained in that condition until his death. He leaves a wife, (his second,) one daugh- ter, (Mrs. Isaac M. Kellogg,) and one son, (William L. Wood,) who is cashier of the Jamaica Bank.
