Keep Up

In military movements, is to preserve that regular pace by which a line or column on a march, or in manœuvring, advances towards any given point without any chasms or fluctuations. When a regiment marches by files, it is almost impo ible for the rear to keep up. On this account, divisions, sub-divisions, and even sections, are best calculated to preserve a regular depth and continuity of march. Keep up likewise signifies to attend to the interior management and discipline of a corps, so as to prevent the least deviation from established rules and regulations. Thus commanding officers are said to keep up good order and discipline, who, whether present or absent, provide against the least insubordination, etc. To keep up a heavy fire , is to play heavy ordnance against a fortified place, or body of men, by a calm and well-directed succe ion of shot. The term is equally applicable to a steady fire of musketry.
