He was educated at private schools and at the United States military academy, where he was graduated in 1836 and promoted to be 2d lieutenant in the 3d artillery. In November of the same year he was transferred to the engineers, but the order was inoperative until July, 1837, when he was made brevet 2d lieutenant of engineers, to date from 1 July, 1836. He was engaged in the construction of the Cumberland road in Ohio till 1840, being promoted 1st lieutenant, 7 July, 1838, and was then on duty till 1847, repairing fortifications at points on the Atlantic coast, and as an assistant to the chief of engineers at Washington. Lieutenant Woodbury was superintending engineer in the construction of Fort Kearny and Fort Laramie for the protection of the Oregon route till 1850, and on fortification duty on the North Carolina coast until 1856, becoming captain of engineers, 3 March, 1853. Thereafter, until the civil war, he was constantly engaged in the duties of his corps on the southern coast, and as an assistant to the chief of engineers. He was promoted major of engineers, 6 August, 1861, assisted in the construction of the defences of Washington, and was with General David Hunter's column at Bull Run. He was made lieutenant-colonel and additional aide-de-camp in September, 1861, and brigadier-general of volunteers, 19 March, 1862, and was assigned to command the engineer brigade in the Army of the Potomac, where he rendered great service in the siege of Yorktown and the construction of roads, bridges, and causeways for the advance upon Richmond and the subsequent change of base to James river. In the Rappahannock campaign of 1862-'3 General Woodbury distinguished himself at Fredericksburg in laying down pontoons under the enemy's fire, and in their prompt removal after the troops had recrossed the river. In March, 1863, he was placed in command of the District of Key West, where he died of yellow fever. He was brevetted to the grade of major-general in the United States army "for gallant and meritorious services during the rebellion," especially on the peninsula in 1862 and at the battle of Fredericksburg. General Woodbury was the author of works on "Sustaining Walls" (Washington, 1845), and the "Theory of the Arch" (New York, 1858).
