According to the Official Records, the North, at the beginning of April, had more than 900,000 soldiers under arms; the South, so far as can be ascertained, not more than 600,000. The Army of the Potomac was receiving constant reinforcements, and at the beginning of April, 130,000 men were encamped on the Stafford Heights. In the West, the whole extent of the Mississippi, with the exception of the hundred miles between Vicksburg and Port Hudson, was held by the Federals, and those important fortresses were both threatened by large armies, acting in concert with a formidable fleet of gunboats. A third army, over 50,000 strong, was posted at Murfreesboro’, in the heart of Tennessee, and large detached forces were operating in Louisiana and Arkansas. The inroads of the enemy in the West, greatly aided by the waterways, were in fact far more serious than in the East; but even in Virginia, although the Army of the Potomac had spent nearly two years in advancing fifty miles, the Federals had a strong foothold.

Louisiana, Texas and Arkansas, the cattle-raising States, were
