The conduct of the advance guard of the 8th Infantry Division at =Beaumont= is worthy of imitation. In this case, the support battalion was deployed and the artillery went into position; strong detachments were retained in rear of the left wing until the main body had arrived. Likewise, a proper relation existed between frontage (4 battalions on a front of 1400 m.) and distribution in depth. According to the General Staff Account of the Franco-German war (II, p. 1045), the distribution was as follows: _First line_: 4th Jäger-Battalion, which was subsequently reinforced by the IInd Battalion, 96th Infantry and the Ist and IInd Battalions, 86th Infantry. _Support for the Artillery_: Füsilier Battalion, 96th Infantry. _Reserve_: IIIrd Battalion, 86th Infantry. We have already mentioned the deployment of the advance guard at =Spicheren= (p. 226 supra). In that instance the whole force was thrown in at once, whereas at =Beaumont= the deployment of the different units was coördinated and proceeded systematically. An advance guard should be able to repulse an attack and then assume the offensive without outside assistance. An example which is not worthy of imitation is the engagement of the 29th Infantry Brigade at the =Hallue=. The brigade began the fight, without being compelled to do so, and deployed its 4530 men on a front of 5000 m. The 30th Infantry Brigade (4070 men) then entered the fight and deployed on a front of 3000 m. in prolongation of the line of the 29th Brigade. If the French had made a decisive attack at this point, the 15th Infantry Division would not have been able to repulse it. Distribution in depth, for the purpose of warding off an enveloping movement and for making a counter-attack, is more necessary in defense than in attack; besides, a greater front may be covered in the former case on account of the smaller losses. The following factors in part determine the extent of front to be occupied and the number of troops required to defend it: (1) the strength, natural or artificial, of the position; (2) obstacles in its front; (3) salient angles which can be easily enveloped; (4) the intentions of the commander (_i.e._, whether he contemplates fighting a purely defensive combat or one including offensive action). =Delaying actions= are usually fought at long and medium ranges as purely passive defensive combats and no provision is made for replacing casualties, the object of the fight being to avoid a decision. Few men should, therefore, be placed in the firing line, but these should be supplied with abundant ammunition. However, as the force desires to avoid a decisive engagement by withdrawing, distribution in depth should be provided to protect the flanks and to facilitate breaking off the action. (Par. 419 German I. D. R.). This requires that distances be great.
