2.—You are Major Black in command of the Advance Guard mentioned in the preceding problem. It is now your mission, of course, to form the advance guard and to tell your captains that you are going to do so, and that you are going to be reinforced by the machine gun company. You ought also to tell them just where your regiment is going to march. You want Companies C and D and the machine gun company to march in the order mentioned, and they are to follow Company B as soon as that company has got its distance. Company C will be the company which is to regulate the pace. Company A is to go out and act as a left flank guard. It is to move by way of the eastern branch of the Carlisle Road while it is on this duty. You ought also to let your captains know all the information about the enemy which has been given to you by your colonel. You want Company B to be the advance party; you want it to go ahead of the remainder of the battalion so that there will be four hundred yards distance between it and the main body. You want to attach Lieutenant Kay, the Battalion Adjutant, and his orderly, to Company B. You want to direct the march of the advance party so that it will know where it is to go. You decide that it shall go by the railroad to the Carlisle Road, and then by the Stock Farm, and on down to the Boyd School House. You are going to be right behind the advance on the march. You want the combat wagons to move out right away, and you want them to go by the cross-roads which is one-quarter of a mile west of Goldenville, and then south on the Carlisle Road, and finally, to join the tail of Company D where the railroad crosses the road. 3.—You are the Company Commander of Company A of the preceding problem. You call your officers and non-commissioned officers together and you give them a verbal order. You tell them that your company is to march as the flank guard of the battalion to which you belong, and you tell them that the enemy possibly has about a regiment in Gettysburg; at least, that is the belief of the Regimental Commander. Your regiment is on its way to Gettysburg. The First Battalion and the machine gun company is going as the advance guard. You want to let your command know that all of the battalion, except yourselves is leaving on the road to the west. You want Lieutenant Johnson, the Second Lieutenant of your company, and the Fourth Platoon, to act as the advance guard to the flank guard, which is the duty on which the company is acting. You want this platoon to march by the country road east of the knoll marked 651, and then you want it to march along the east branch of the Carlisle Road. The distance you decide upon for the advance guard to be in front of the main body is 500 yards.
