Mail was to leave the camp at 12 today; sat down to write a letter before I was ½ through was detailed to take charge of a squad of 30 men with spades for fatigue & report with them at Div Hd. qtrs. I reported with the detail at 11. A. M. some mistake had been made with reference to the detail as the A. A. G. expicted my detail to have axes. waited with the men until he rode to Brig. Hd. qtrs to ascertain how the mistake had occurred, he returned at 12, M. & ordered me to report at a two gun battery. on the left & near Spanish fort. I found the battery & put the men to work to finish it. The 1st Ind heavy Artilery mount 2 30 lb Parrots here while we are at work. These guns are intended to play on the Rebel water battery which annoys us more than all their other guns, while we were at work a staff officer rode around giving orders for all the batteries around the whole line to open out at 5 P. M. & fire 40 ronds to each gun, with intervals of 3 mins. finished the battery a little before 4. but had to hold the detail to tear down a breastwork in front of it which was to come down just before time to open out, at 20 mins before 5 Capt of Battery ordered the work down, men all worked lively as there was danger of the Rebs firing on the party, two men having been wounded here yesterday. Just 3 mins before 5 finished that job & falling the men in started for camp about ¾ mile distant & if the Rebs replied to our batteries in point blank range, had not advanced from the battery more than 200 yds until the whole part of our line was ablaze, walked fast to camp. Rebs did not reply & no accidents occurred. after arrived in camp the Jonnies lifted a few shot over, they tried to sharpshoot our gunners from their fort & sent the balls uncomfortably close. The 33d Mo. & 35th Iowa & 12th Iowa moved in this evening again to our camp our Brig is ordered to the left to fill the places of these Regts. At 8. P. M. fall in & move in the darkness with a little sprinkle of rain 1 mile to the left of our camp, find very poor quarters, lie down almost anywhere for the night.
