July 1st. On duty in the trenches; pickets unusually lively. They are extremely hostile toward us. On the left, along the Fifth Corps line, there is no firing by day, and the men from both armies get water from a spring between the lines. Here there is no cessation by day or night. It may be caused by the nearness of our line, the suspicion of a sudden attack, or because of the presence of colored troops in our working parties. Our losses are severe, averaging fifteen a day on our division line. Corporal James H. Barry, of Company I, a gallant soldier, who was wounded May 6th, was killed in the trenches to-day by a sharp-shooter. At night the regiment retired to the woods.

July 2d and 3d. On duty in the rear. Heavy siege guns were sent to the front to be placed in a new battery to be built in our line. On the 3d we were mustered for pay. The line was short, indeed, compared with our last muster, at Catlett's Station. How many in that brief time have gone from the toils and pains and hardships of a soldier's life to sleep in soldiers' graves! How many names are to-day transferred from the rolls of these companies to the roll of the honored dead! To-day the Sanitary and Christian Commissions sent a generous supply of hospital and other stores, to aid in celebrating the national holiday to-morrow. These were distributed equally among the companies. The staff of our national color was shattered by a bullet to-day. Both staves are now broken, and the flags are riddled with bullet-holes. They are also stained with the blood of heroes who have borne them unto death. At dark we relieved the Second Brigade.

July 4th. Regiment in the trenches. The heat was intense, and the men pitched their shelter-tents over the top of the trenches. This kept out the sun, but excluded also the air. General Burnside and the division commanders were on the front line together in the afternoon, and the regimental prophets predicted an immediate attack; but the hours dragged along, and the day proved to be remarkably quiet. A request was transmitted to the State authorities for a new stand of colors. One year ago we commenced the Jackson campaign, which proved so disastrous to the regiment. The anniversary was frequently mentioned by the men. Then we hoped to spend this day in peace at home. Now we dare not hope for a speedy ending of the war. Then Gettysburg and Vicksburg encouraged the belief that the weight of the struggle had passed. Now Atlanta, Petersburg, and Richmond, bid prolonged defiance. But the end is coming!

July 5th. Passed without incident. Firing less severe than usual. The monotony of siege life unbroken. Regiment relieved at nine in the evening.

July 6th. First Lieutenant Fairbank received his commission as Captain, vice Warriner, resigned, and was mustered in. Information was received that all the vacancies among the commissioned officers have been filled by promotions from the ranks. This information was received with pleasure, as it will increase the working-force and efficiency of the regiment. To-day private H. A. Murdoch, of Company H, was wounded in the arm.

July 7th. To-day the Fourth Rhode Island arrived from Yorktown via City Point, and was assigned to our brigade. Its commander, Colonel W. H. P. Steere, being the senior officer, assumed command of the brigade. More sanitary supplies, consisting of twenty-five pounds of white sugar, a dozen cans of milk, vegetables, a few bottles of sherry, brandy, etc., were received from the Commissions, and distributed among the sick. There is much sickness in the command. The extreme heat, arduous duty, and constant exposure to danger, are wearing on men who up to this time have borne all the hardships of the campaign. At night the regiment relieved the troops in the picket line, in the old position. The works daily show the labor expended upon them. They are now very strong, and their condition much improved. Rumors prevail that an assault is to be made to-morrow.

July 8th. The duty in the trenches to-day was very severe, owing to the intense heat, and the sharp, incessant firing. Our men had good range, and replied to the enemy shot for shot. Enemy on the alert, and asking about the mine. They regard it as a great joke, and threaten to countermine. More rumors of an assault from our front. Lately our men discovered an ice-house in front of our line, a little to the left of our position, and for a while it has been neutral ground for one or two men from the opposing lines to get ice, to the extent that if any one has been seen near the ice-house they have not been fired upon. To-day, however, Corporal Lucius Lowell, of Company F, in endeavoring to get some ice, was fired upon, and received two bad wounds in the breast and wrist.

July 9th. Still on duty in the trenches. Intensely hot. To-day we received the cheering news of the sinking of the rebel pirate "Alabama" by the United States Steamer "Kearsarge." This information was received with loud cheering. The rebels across the way wanted to know the cause of our joy, and were answered by a double-shotted salute from all our artillery, which made them burrow for an hour. At night we were relieved.

July 10th. In the woods, suffering from intense heat, and tormented by myriads of flies, which were as hostile as the rebel pickets in our front. Sergeant Thomas H. Haskell, who was wounded in the right hand at Spottsylvania, and yesterday, though not fully recovered, returned to duty with a First Lieutenant's commission, was mustered and assigned to the command of Company B. Several enlisted men also returned, and the effective strength at night was one hundred and ninety; six commissioned officers and one hundred and eighty-four enlisted men, with fourteen sick in the hospital.

July 11th. The day was very hot, relieved by showers at night. At nine o'clock the regiment went to the front and relieved the Seventeenth Vermont on picket. To-day a siege order was issued from army head-quarters, regulating the operations of the siege.
