On October first the Brigade moved in pusuit of Hood's army which was heading north, hoping Sherman would abandon Atlanta and follow him. Sherman merely sent a division after him and continued his march to the sea. On the 2nd and 3rd of October the brigade engaged the rebel rear in a lively skirmish at Sweet Water Creek with slight loss; on the 4th of October joined the Division at Marietta. On the 5th the division attacked the rear guard at Alatoona Pass, crushing it and capturing over one hundred prisoners. On the 6th, the brigade attacked and cut to pieces a whole brigade, capturing a brigadier general and over five hundred prisoners. Hood retreated to his old works at Dallas. The division assaulted him here and drove him out, capturing one piece of artillery. On October 12th, Confederate cavalry under General Joseph Wheeler was reported to be west of Rome, Georgia. As the US 2nd Cavalry Division, of which the 7th Pennsylvania was a part, was re-forming after having crossed the two rivers at Rome, rebels attacked the pickets about 1/4 mile from the main body on the Coosaville Road. A patrol found the rebels too strong to attack mounted; there were nearly 1200 rebels to 300 cavalry, thus outnumbering the Division 4 to 1. Still they drove the rebels out of their breastworks, sending dismounted men and horses fleeing in confusion. The command was then formed in the breastworks and, it being late, settled in for the night. At 6:30 am on the 13th of October, the Second Brigade, consisting of the 7th Pennsylvania, 4th Michigan, and the 4th US Regular Cavalries, led the advance. Brigadier General Kennard Garrard, Commander of the 2nd Cavalry Division, states in his Official Report: "On the 13th the enemy's cavalry appeared on the hills west of Rome. The Division crossed...and then drove the enemy away and five miles down the road toward Coosaville...After advancing some four miles, we struck the enemy. The 1st Ohio was dismounted as skirmishers, and the 3rd Ohio was sent out on the flanks mounted, and the 3rd Brigade was brought up in line, two Regiments on each side of the road. The advance was ordered and the Second Brigade was ordered up." Colonel Burns stated: "All then moved forward... when we arrived at the top of the hill in sight of the rebel gunners they opened on us with their artillery. We moved at a walk about a third of a mile when we were ordered to charge! Away we went with the most infernal yelling and cheering, the Seventh in the advance!" General Garrard continues: "The enemy, after a little skirmishing, fellback but our advance continued. Soon the enemy opened artillery... when within long rifle-range of their position the woods ended, and large open cornfields lay between us and the enemy, who had formed a line beyond a creek on a ridge in the edge of some timber. The enemy stood firing his artillery up to the last moment, and the cannoneers used their pistols in defense of their pieces. The artillery, two pieces, was captured...the enemy was routed and pursued on several roads. Their killed, wounded, and captured was over 70, but every pursuing party reported large numbers left wounded or killed on the roads or in the woods. The main body was pursued on the Coosaville Road 14 miles below Rome. The enemy was completely routed, and I learned afterward it was more than three days before this Rebel Division could be collected together again."
