On the morning of the 10th, Captain Lyon's command moved from various points, so as to surround the Rebel camp at three o'clock in the afternoon.

At that hour General Frost, the Rebel commander, was surprised at the appearance of an overpowering force on the hills surrounding his position.

A demand for surrender gave half an hour for deliberation.

At the end of that time General Frost concluded to capitulate.

The prisoners, less than a thousand in number, were marched to the arsenal and safely secured.
This achievement destroyed Camp Jackson, and established the United States authority in full force over St.Louis.An unfortunate collision occurred between the soldiers and the crowd outside.
Provoked by insults terminating in an assault with fire-arms, a portion of the German troops fired upon the multitude.
