Cornicen

The cornicen's job was to signal salutes to officers and sound orders to the legions.

The classicum, which is a particular sound of the buccina or horn, is appropriated to the commander-in-chief and is used in the presence of the general, or at the execution of a soldier, as a mark of its being done by his authority.

The ordinary guards and outposts are always mounted and relieved by the sound of trumpet, which also directs the motions of the soldiers on working parties and on field days.

These rules must be punctually observed in all exercises and reviews so that the soldiers may be ready to obey them in action without hesitation according to the general's orders either to charge or halt, to pursue the enemy or to retire.

For reason will convince us that what is necessary to be performed in the heat of action should constantly be practiced in the leisure of peace.
