It may be thought that the duties of the Signal Corps were always performed in positions where their personal safety was never imperilled. But such was far from the fact. At the battle of Atlanta, July 22, 1864, a signal officer had climbed a tall pine-tree, for the purpose of directing the fire of a section of Union artillery, which was stationed at its foot, the country being so wooded and broken that the artillerists could not certainly see the position of the enemy. The officer had nailed a succession of cleats up the trunk, and was on the platform which he had made in the top of the tree, acting as signal officer, when the Rebels made a charge, capturing the two guns, and shot the officer dead at his post.
During the battle of Gettysburg, or, at least, while Sickles was contending at the Peach Orchard against odds, the signal men had their flags flying from Little Round Top; but when the day was lost, and Hood with his Texans pressed towards that important point, the signal officers folded their flags, and prepared to visit other and less dangerous scenes. At that moment, however, General Warren of the Fifth Corps appeared, and ordered them to keep their signals waving as if a host were immediately behind them, which they did.
From the important nature of the duties which they performed, the enemy could not look upon them with very tender regard, and this fact they made apparent on every opportunity. Here is an incident which, I think, has never been published:—
When General Nelson’s division arrived at Shiloh, Lieutenant Joseph Hinson, commanding the Signal Corps attached to it, crossed the Tennessee and reported to General Buell, after which he established a station on that side of the river, from which messages were sent having reference to the disposition of Nelson’s troops. The crowd of stragglers (presumably from Grant’s army) was so great as to continually obstruct his view, and in consequence he pressed into service a guard from among the stragglers themselves to keep his view clear, and placed his associate, Lieutenant Hart, in charge. Presently General Grant himself came riding up the bank, and, as luck would have it, came into Lieutenant Hinson’s line of vision. Catching sight of a cavalry boot, without stopping to see who was in it, in his impatience, Lieutenant Hart sang out: “Git out of the way there! Ain’t you got no sense?” Whereupon Grant very quietly apologized for his carelessness, and rode over to the side of General Buell. When the lieutenant found he had been addressing or “dressing” a major-general, his confusion can be imagined. (See [frontispiece]).
One more incident illustrating the utility of signalling will close the chapter:—
After arriving before Fort McAllister, General Sherman sent General Hazen down the right bank of the Ogeechee to take the fort by assault, and himself rode down the left bank to a rice plantation, where General Howard had established a signal station to overlook the river and watch for vessels. The station was built on the top of a rice-mill. From this point the fort was visible, three miles away. In due time a commotion in the fort indicated the approach of Hazen’s troops, and the signal officer discovered a signal flag about three miles above the fort, which he found was Hazen’s, the latter inquiring if Sherman was there. He was answered affirmatively, and informed that Sherman expected the fort to be carried before night. Finally Hazen signalled that he was ready, and was told to go ahead. Meanwhile, a small United States steamer had been descried coming up the river, and, noticing the party at the rice-mill, the following dialogue between signal flags ensued:—
“Who are you?”
“General Sherman.”
“Is Fort McAllister taken?”
“Not yet; but it will be in a minute.”
