On 17 March 1864, the Springfield Illinois Light Artillery was reunited and participated in Steele's Camden Expedition from 23 March–3 May 1864. During the campaign, Vaughn's Battery was part of the artillery contingent of Frederick Salomon's 3rd Division. Steele's effective force numbered 13,000 troops of which about 2,500 became casualties. There was a skirmish at Okolona on 2–3 April. The Battle of Prairie D'Ane occurred on 9–12 April. Steele's VII Corps seized Camden but was unable to maintain its position because Confederate cavalry wrecked two supply convoys at Poison Spring and Marks' Mills. On 26 April, Steele's force abandoned Camden and marched back toward Little Rock. The Federal column reached the Saline River on 29 April and paused while the engineers built a pontoon bridge across the rain-swollen stream. The Battle of Jenkins' Ferry was fought on 30 April. Though outnumbered, Salomon's soldiers improvised defensive positions on the south bank and repulsed repeated Confederate assaults during the morning. After the last attack ended at 12:30 pm, Salomon's division withdrew across the river and destroyed the pontoon bridge. The Federals reported 63 killed, 413 wounded, and 45 missing, while Confederate returns showed 86 killed, 356 wounded, and one missing. Steele's force continued its retreat to Little Rock.
