Gen. Burnside could not maintain his advantage, and was obliged to withdraw from the extreme position which he had gained to one slightly in rear. He, however, held his bank of the river completely, and maintained much ground beyond it which he had taken from the enemy. During the advance on the left Gen. Rodman was wounded. Notwithstanding substantial and decided successes of the day, the Federal forces had suffered so severely during the conflict, having lost 11,426 killed and wounded, and among them many general and superior officers, that it was deemed prudent by Gen. McClellan to reorganize and give rest and refreshment to the troops before renewing the attack. The 18th was accordingly devoted to those objects. On the night of the 18th, however, Gen. Lee withdrew his forces hastily across the Potomac, abandoning further contest with the Union forces, and yielding all hopes of further remaining on Maryland soil. The Confederate army is supposed to have lost nearly 30,000 men during its brief campaign in Maryland. The Federal forces captured 39 colors, 13 guns, more than 15,000 small-arms, and more than 6000 prisoners.--_Extracts from D.

The fortress communicated with the northern and western porticoes of the temple area, so that the garrison could at any time enter the courts of the temple and prevent tumults. Josephus describes it as standing on a rock 50 cubits high, and having everything necessary within itself. =Antustriones.= A body-guard of the kings or chiefs of the ancient Germans, which was composed of volunteers.
