Major-General Lloyd Tilghman, of the rebel army, was a native of Maryland, and nearly fifty years of age. He was appointed to West Point Military Academy as a cadet in 1831, and graduated on the 30th of June, 1836, standing last but three in a class of forty-nine members. On the 1st of July, 1836, he was breveted a second lieutenant of the First dragoons, rather a high brevet for an officer occupying so low a grade in the Academy; but when we consider who were the appointing officers at that time, and the position the same men held in the war, our readers need not wonder at the appointment. Three days after that date he received his full commission and after being in the army for three months he resigned, plainly showing that he merely wished to gain a military education at the expense of the United States government, for which he gave nothing in return but rebellion. During the remainder of 1836 and the subsequent year he was appointed to the lucrative position of division engineer of the Baltimore and Susquehanna Railroad, followed immediately by that of assistant engineer in the survey of the Norfolk and Wilmington Canal of Virginia. He was next appointed (1838–9) assistant engineer of the Eastern Shore Railroad of Maryland, and in 1839–40 of the Baltimore and Ohio Railroad. During 1840 he was also engaged in the survey of the public improvements of Baltimore. For the next few years he held no important public position; but the Mexican war again brought him into notoriety. He first served as volunteer aid to General Twiggs in the battles of Palo Alto and Resaca de la Palma, Texas, May, 1846, and doubtless here learned some of his early military lessons. Orders were now sent back to General Sherman to turn his corps toward Bridgeport, and General Blair was expected to join him at that place. Bridgeport was on the Black river, and some miles north of the railroad. By crossing the river at that point, General Sherman would be on the flank of the enemy, if they made a stand at the railroad crossing of the river. BATTLE OF BIG BLACK BRIDGE, MISS. MAY 17, 1863. The battle of Big Black Bridge was fought on Sunday, the 17th, the day after the battle of Champion’s Hill. In this spirited engagement only the Thirteenth army corps was engaged. In the morning, after a bivouac on the hill overlooking the village of Edwards’ Station, the column, with McClernand at its head, moved towards Black river bridge.
