Day One Highest Losses: No. 5

As Forney's and Barksdale's Divisions were trying to hold onto Sagarville and fighting back a midday assault by the Army of the South Branch's I Corps and V Corps, Brigadier General Alfred Colquitt's Division arrived at Debussy on the Madison Pike from Mt. Zion Church. Colquitt was ordered to deploy south of Debussy and started moving south on a trail through the woods on the west bank of Trout Run.

At the same time, the 4th Division, V Corps (Major General William Rosecrans) had been ordered to extend the Union left. Rosecrans' Division had been resting near Colvin and had not taken part in the fighting during the morning. To move to the Union left, Rosecrans moved his division east on Kingston Road and then north on a path through the woods along the west bank of Trout Run. His intention was to move east again to support the left flank of Major General Abner Doubleday's 2nd Division V Corps, engaged near Finch's Woods. Rosecrans' men would never arrive on Doubleday's left, because they were on a collision course with Colquitt.

The two divisions literally ran into each other in the woods without time to deploy. The fighting became a jumbled mess, with minimal brigade cohesion.  One of Colquitt's Brigades was Pettigrew's Brigade, commander by Brigadier General James Pettigrew. Pettigrew fell early in the fighting, killed by men from the 123rd New York (3rd Brigade, 4th Division, V Corps). The 123rd was in turn captured by the 13th South Carolina, one of Pettigrew's regiments. The 13th was then routed by the 107th Pennsylvania, 9th Ohio and 3rd New Jersey, representing three different brigades of their division. 

Pettigrew's Brigade fought valiantly, with the 2nd South Caroline killing Brigade General Alfred E. Torbert and capturing the 13th New Jersey from the 4th (New Jersey) Brigade of Rosecrans' Division. The 2nd South Carolina was then routed by the 2nd New Jersey.  By the end of the day, Pettigrew's Brigade had only one regiment left (14th South Carolina) whose commander (Colonel Abner Perrin) assumed command of the brigade. Despite heavy losses, the brigade is expected to return to the field on the morning of Day Two of the campaign.
