The deep column is employed for assembling troops if the terrain necessitates a formation on a narrow front. If sufficient distance is allowed between companies, line may be formed to a flank, but this increases the depth of the column to such an extent that movements at attention are impossible. The deep column may be used as a route formation in addition to the column of squads. During the change from route formation to that of action, the deep column formation may be retained so long as the depth of the whole column does not have to be further reduced. When necessary, the deep column may be replaced by a formation in which the four companies, each in route column, are placed abreast of each other. The broad column finds proper employment, aside from parades, in cases where the terrain or the contemplated deployment requires more front than depth. It is also advisable to assemble the widely scattered troops in a broad column after an action. The broad column does not lend itself, however, to the execution of changes of front by battalion; but should such changes of front become necessary, they are always to be executed by company. The color is posted between the right and left center companies, in broad column, and on the right flank of the third company, in deep column. In action the color remains with the company with which it happens to be at the moment.[77] Should this company also join the firing line, the color accompanies it; but under all circumstances one squad must remain with the color. (Par. 236 German I. D. R.). It has been contended that this is a disadvantage, as the enemy can direct his fire on the color and the men in its vicinity. If the colors, upon which the soldiers have been sworn, are taken into the field, it is always better to endure the unavoidable losses incidental to carrying them, and even to expose them to capture, than to send them back to a safe place under escort.[78] At the Albrechtshaus farm (Wörth) the colors served as rallying points around which the disordered skirmishers rapidly assembled.[79] [77] In Japan the color joins the battalion commander. British troops leave their colors in their garrisons. In Russia and France the color is carried only by one battalion of each regiment.

A platoon of the Füsilier-Battalion of the 47th Infantry was sent to the rear with the color, and a squad of the Füsilier-Battalion of the 46th Infantry finally had six colors to guard. In the 88th Infantry, out of a total of 48 sections, 9 sections remained in rear as a guard for 2 colors, but finally 6 of these sections crossed the Sauer.
