Man, Isle of. An island of Great Britain, in the Irish Sea, nearly equidistant from the coasts of England, Scotland, and Ireland. It was subdued by the king of Northumberland, 621; by Magnus of Norway, 1092; ceded to the Scots, 1266, and taken from them in 1314 by Montacute, afterwards earl of Salisbury; it subsequently fell to the Earl of Derby. The brave Countess of Derby held this island against the troops of the Parliament in 1651, after her husband had been beheaded at Bolton, England, in the same year for his devotion to the royal cause.

Manassas. A town in Prince William Co., Va., which was an important military position during the civil war, and where the Alexandria and Manassas Gap Railways meet, near a creek called Bull Run; it was held by the Confederates in 1861, when they were attacked by the Federal general Irvin McDowell. He began his march from Washington on July 16, and gained some advantage on the 18th at Centreville. On the 21st was fought the first battle of Bull Run. The Federals, who began the fight, had the advantage till about 3 o’clock P.M., when the Confederate general Johnston brought up reinforcements, which at first the Federals took for their own troops. After a brief resistance, the latter were seized with sudden panic, and in spite of the utmost efforts of their officers, fled in disgraceful rout, abandoning a large quantity of arms, ammunition, and baggage. The Confederate generals, Johnston and Beauregard, did not think it prudent to pursue the fugitives, who did not halt till they reached Washington. The Federal army is said to have had 481 killed, 1011 wounded, and 1216 missing. The loss of the Confederates was stated to be about 1500. In March, 1862, when the Army of the Potomac under Gen. McClellan marched into Virginia, they found that the Confederates had quietly retreated from the camp at Manassas. On August 30, 1862, this place was the site of another great battle between the Northern and Southern armies. In August, Gen. “Stonewall” Jackson, after compelling the Federal general Pope to retreat, defeated him at Cedar Mountain on the 9th, turned his flank on the 22d, and arriving at Manassas repulsed his attacks on the 29th. On the 30th, Gen. R. E. Lee (who had defeated Gen. McClellan and the invading Northern army before Richmond, June 26 to July 1) joined Jackson with his army, and Pope received reinforcements from Washington. A desperate conflict ensued, which ended in the Confederates gaining a decisive victory, compelling the Federals to a hasty retreat to Centreville, where they were once more routed, September 1. The remains of their army took refuge behind the lines of Washington on September 2. Pope was at once superseded, and McClellan resumed the command to march against the Confederates, who had crossed the Potomac and entered Maryland.
