Military history tells us that an army corps consisting of 25 battalions, acting as a part of a larger force in a deliberately planned attack, occupies an average front of 2.5 to 5 km. According to this, the frontage of a brigade would amount to about 800-1000 m., _i.e._, to 6-7.5 rifles per meter of front. This limit was frequently exceeded during the =Franco-German war= according to the circumstances under which the brigade went into action and the commander’s estimate of the situation. If the brigades had to cover the concentration of the columns in rear, and if the battalions came into action successively, both brigade and battalion frontages were frequently very great. The endeavor to close with the enemy as soon as possible and the desire to bring a large number of rifles into action, led to enormously increased frontages at the expense of depth. The brigades which arrived later, entered the line where other brigades were already engaged, and the result was a dissolution and admixture of all tactical organizations. At =Colombey=, the 25th Brigade covered a front of nearly 3 km. with 28 companies, only four or five companies remaining in close order. Connecting with this brigade on the north, 22 companies, belonging to two different divisions of the 1st Army Corps, covered a front of 4 km., supported by three or four companies in close order. With such an overextension of front the offensive or defensive power of a force is, of course, crippled. During the battle of =Amiens=, the 3rd Prussian Brigade advanced in three columns against the heights north of the Luce. On the left, six companies of the 4th Infantry advanced from Domart, in the center, four companies from Hangard, and on the right, two companies from Demnin. A battery and a troop (_Eskadron_) were attached to each column, and the right column was followed by the 44th Infantry. The French advanced troops were pushed back without special difficulty, but at the northern edge of the timber, the brigade now found itself opposite the French main position Cachy--Villers-Bretonneux. The attack on this position began at once, and in a short time the 4th Infantry and two batteries were in action on the line East corner of the Bois de Hangard--Gentelles (5 km. long). At the same time, the 44th Infantry with one battery deployed on a front of about 2000 m. to the right of this line. The right wing of the 44th Infantry subsequently advanced to attack the trenches southeast of Villers-Bretonneux and captured them. The enveloped French left wing withdrew to the village named, and rallied on strong reserves. This was the situation when the fight came to a standstill toward 1 o’clock P. M. The brigade fought in a thin line over a mile (four English miles) long. The reserve only consisted of three companies of the 4th Infantry, at Gentelles, and four companies of the 44th Infantry, in rear of the right flank.
