Petersburg. A city of Dinwiddie Co., Va., on the south bank of the Appomattox River, about 25 miles from Richmond. The city is one of historic interest. It was twice occupied by the British forces as headquarters during the Revolutionary war; but it is principally noted as the scene of several sanguinary encounters during the civil war, and for the obstinate and bloody defense which it made. On June 15-16, 1864, two formidable assaults were made on it by the Army of the Potomac under Gen. Grant, but they were repulsed with heavy loss. It was then determined to invest the city, which was done a few days later. On July 30, another attempt was made to take it by storm, but without success. The siege was prolonged with many indecisive operations until April 3, 1865, after a week’s bombardment it was evacuated by Gen. Lee, who surrendered six days later.

It is the residence of the general commandant of the Slavonian military frontier, and of several subordinate military authorities. It derives its present name from Peter the Hermit, who here marshaled the soldiers of the first Crusade. Peterwardein was taken by the Turks, July, 1526. In 1688, the fortifications were blown up by the Imperialists, and the town was soon after burned to the ground by the Turks; but at the peace of Passarowitz, on July 21, 1718, it remained in the possession of the emperor. It was here that, on August 5, 1716, the Austrians, under Prince Eugène, obtained a great victory over the Turks under Grand Vizer Ali; the latter then lost their last footing in Central Europe.
