ROULER, Fr. To be subject to a fixed roster according to rank and precedence.

ROUND. From the French ronde. In military matters, a visitation; a personal attendance through a certain circuit of ground, to see that all is well. A round consists, in the ordinary way, of a detachment from the main-guard, of an officer or a non-commissioned officer and 6 men, who go round the rampart of a garrison, to listen if any thing be stirring without the place, and to see that the sentinels be diligent upon their duty, and all in order. In strict garrisons the rounds go every half hour. The sentinels are to challenge at a distance, and to port their arms as the round passes. All guards turn out, challenge, exchange the parole, and present arms, &c.

Rounds, are ordinary and extraordinary. The ordinary rounds are three: the town major’s round, the grand round, and the visiting round.

Manner of going the Rounds. When the town major goes his round, he comes to the main-guard, and demands a serjeant and four or six men to escort him to the next guard; and when it is dark, one of the men is to carry a light.

As soon as the sentry at the guard perceives the round coming, he shall give notice to the guard, that they may be ready to turn out when ordered; and when the round is advanced within about 20 or 30 paces of the guard, he is to challenge briskly; and when he is answered by the serjeant who attends the round, town major’s round, he is to say, stand, round! and port his arms: after which he is to call out immediately, serjeant, turn out the guard! town major’s round. Upon the sentry calling the serjeant to turn out the guard, he immediately draws up the men in good order with shouldered arms, and the officer places himself at the head of it, with his sword drawn. He then orders the serjeant and four or six men to advance towards the round, and challenge: the serjeant of the round is to answer, town major’s round; upon which the serjeant of the guard replies, advance, serjeant, with the parole! at the same time ordering his men to rest their arms. The serjeant of the round advances alone, and gives the serjeant of the guard the parole in his ear, that none else may hear it; during which period, the serjeant of the guard holds the point of his bayonet or sword at the other’s breast. The serjeant of the round then returns to his post, whilst the serjeant of the guard, leaving his men to keep the round from advancing, gives the parole to his officer. This being found right, the officer orders his serjeant to return to his men; says, advance, town major’s round! and orders the guard to port their arms; upon which the serjeant of the guard orders his men to wheel back from the centre, and form a lane, through which the town major is to pass (the escort remaining where it was) and go up to the officer and give him the parole, laying his mouth to his ear. The officer holds the point of his sword at the town major’s breast while he gives him the parole.

Grand Rounds. The rounds which are gone by general officers, governors, commandants, or field officers. When there are no officers of the day on piquet, the officer of the main guard in garrison may go the grand rounds.

Visiting Rounds. Rounds gone by captains, subalterns, and the town majors of garrisons.

The grand rounds generally go at midnight; the visiting rounds at intermediate periods, between sunset and the reveille. The grand rounds receive the parole, and all other rounds give it to the guards.

There is also a species of subordinate rounds which are performed by a corporal and a file of men; and which are in reality nothing more than a patrole. When challenged they answer patrole rounds.

The governor of a garrison can order the rounds to go as often as he may judge expedient. Extraordinary rounds are resorted to when any particular event or occurrence is expected, and in cases of tumult, &c.
