Chamber. In howitzers, and mortars of the old model, was the smallest part of the bore, and contained the charge of powder. In the howitzers the chamber was cylindrical, and was united with the large cylinder of the bore by a conical surface; the angles of intersection of the conical surface with the cylinders of the bore and chamber were rounded (in profile) by arcs of circles. In the 8-inch howitzer, the chamber was united with the cylinder of the bore by spherical surface, in order that the shell might, when necessary, be inserted without a sabot. The chamber is omitted in all cannon of the late models, the cylinder of the bore terminating at the bottom in a semi-ellipsoid. The old chambers were subcaliber. The first use of a chamber larger than the bore occurred, it is believed, in a gun invented by an American named Ferris. The gun had a great range. One of the most important improvements in recent ordnance consists in the use of this chamber. The English, who deserve the credit of first appreciating it, now use it in all their largest guns. See [Ordnance, History of].

Chancellorsville. A small village of Spottsylvania Co., Va., near the Rappahannock River, about 65 miles north by west from Richmond. This place was the scene of several sanguinary conflicts between the Federal army of the Potomac under Gen. Hooker and the Confederates under Gen. Lee. On April 28, 1863, the Federal army crossed the Rappahannock; on May 2, Gen. “Stonewall” Jackson furiously attacked and routed the right wing, but was mortally wounded by his own party firing on him by mistake. Gen. Stuart took his command, and after a severe conflict on May 3 and 4, with great loss to both parties, the Federals were compelled to recross the Rappahannock. The struggle was compared to that at Hougoumont during the battle of Waterloo.
