Sedgwick was constantly moving during the day, it was not much used. During the morning, Lieutenants [James B.] Brooks and [William H.] Hill were in a fine position in the church tower in the city of Fredericksburg, and reported to General Sedgwick and the Phillips house. In the afternoon they moved forward to the heights. At 5 p. m., all the troops having moved from the vicinity of this station, and it being very much exposed, I directed its discontinuance. Before these officers had time to leave, they were shelled by the rebels, who were rapidly regaining the ground they had lost in the morning. The rapidity of the movement caused a separation of the party, and Lieutenant Hill reported to me at the Phillips house. He there reported the facts of the case to Major [George F.] Barstow, assistant adjutant-general, who had been sent to the Phillips house to ascertain the news. Captain Gloskoski and Lieutenant Marston [each] opened a station this morning upon the heights of Fredericksburg, but they were not used. At 5.30 p. m. Lieutenant Jerome reported that his men had swam the river with their wire, and that he had established a telegraph station on the south bank of the river, near Banks' Ford, with the line of skirmishers. This movement, though bold and daring, was of no immediate importance, and the instruments and wire were brought back in the evening.
May 4, 1863. - The enemy had occupied the hills of Fredericksburg at an early hour this morning, driving Captains Babcock and Gloskoski and [Lieutenant] Marston from their stations. Lieutenant Marston returned to the Phillips house, and I immediately sent him to the chief of staff to report matters. Captains Babcock and Glockoski escaped toward General Sedgwick. Communication by the signal telegraph was opened from the Phillips house to headquarters camp, forming an intermediate station. This station was available to communicate observations to headquarters, and to communicate to the Lacy house. The station in Fredericksburg was withdrawn this morning, as there was no one to report to, and I did not wish to leave it there in a useless position. During the morning, General Sedgwick's forces being cut off from General Hooker and from Fredericksburg, it was of immense importance that communication should be established with him. His orders prevented him from using his signal officers for that purpose. I was very much afraid no communication could be opened. It was impossible to send any orders to him countermanding the orders received two nights before, and it seemed impossible to call attention by signals until Captains Gloskoski and Babcock established a station near the Guest house, and near General Sedgwick's headquarters. These officers had not been informed of the order prohibiting the use of signals, and consequently opened communication. I considered the necessity of keeping communication open so great as to excuse me for ordering, on my own responsibility, that the station should be held as long as possible. The same order was also given by General Sedgwick, and during the day this station was of eminent importance, as Captain Hall and Lieutenant [Peter A.] Taylor at the Phillips house kept General Sedgwick thoroughly informed of the movements of the enemy. These messages passed over the heads of the enemy, and must have been of great assistance. Many important messages were sent by others in the same way. My directions were that all messages should be sent in cipher. This station was kept open until General Sedgwick was forced to retire from his position, and was for a long time exposed very much to the fire of the enemy. During the morning, the officers, who had been stationed by me at Banks' Ford on the 1st of May had succeeded in opening communication with the extreme right of General Sedgwick, so
