same results. The horse artillery was also partially engaged at South Mountain, on the roads to Boonsborough, Hagerstown, Sharpsburg and in various affairs in front and on the flanks od the army, and always discharged its duties in a manner worthy of the reputation in had acquired in similar service. Its duties were arduous, requiring constant watchfulness, enterprise, and labor on the part of officers and men, and the horses, often on scant forage, were in harness for a week or ten days, day and night. For special information on these parts of their service, I beg leave to refer to the reports of the commanders of cavalry under whom they served.
At the battle of South Mountain (September 14), Gibson's, Benjamin's, Stewart's, and McMullin's batteries were engaged and rendered excellent service. Stewart's battery being attached to Gibson's brigade in its attack on the enemy on the right of the National road, one of McMullin's sections was moved by hand to the top of South Mountain under a severe fire, and opened at close range on the enemy. In this affair Lieutenant Crome, commanding the section, was killed.
From the artillery of General Franklin's command in the battle at Crampton's Pass I have received no reports. They were made to division commanders.
On the evening of September 15, the enemy opened a heavy artillery fire on our advance near the Antietam, and were replied to by a portion of our own, particularly by Tidball's battery of horse artillery, which maintained a cannonade against a largely superior force of the enemy's guns from early in the afternoon until near dark.
At sunset I received orders from Major-General McClellan in person to select places for our guns of position. They were posted next morning, under the direction of Lieutenant-Colonel Hays, commanding the Artillery Reserve, on the positions indicated-the long ridge on the eastern branch of the Antietam, overlooking the field of battle of the next day. Taft's, Langner's, Von Kleiser's, and Wever's batteries were placed on the ridge between the turnpike bridge and the house occupied as general headquarters (Pry's). The enemy soon opened upon them. The fire was promptly returned, and the enemy ceased his fire and withdrew his guns. In this cannonade Major Albert Arndt, commanding the First (German) Battalion New York Artillery, an experienced and excellent officer, was mortally wounded while personally directing one of his guns, and died on the 18th.
During the afternoon Taft's and Von Kleiser's batteries were moved to the heights below the ridge. At daylight on the 17th, Hazlett's battery was placed in the position occupied on the day before by Taft's; Durell's and Weed's were stationed farther down on the crest; Kusserow's on the height overlooking the bridge and sweeping its approaches; Benjamin's still farther to the left and rear, overlooking Sharpsburg and the country below it, and near Benjamin's were planted a couple of rifle boat howitzers. These completed the line of guns of position. They overlooked the enemy, and swept most of the ground between them and our troops. They were well served, especially the guns of Benjamin's battery. Their field of fire was extensive, and they were usefully employed all day, and so constantly that the supply of ammunition for the 20-pounders ran short.
In the course of the afternoon a rifled battery of the Reserve Artillery was asked for by General Hancock, who succeeded General Richardson in the command of his division when the latter was wounded. There was none disposable; all were actively engaged or had been detached to other points, but Graham's light 12's were sent instead. This battery
