Second Battle of Mesilla
The Second Battle of Mesilla was an unusual engagement of the American Civil War. It was fought on July 1, 1862, and was the last engagement between Union and Confederate forces in the Arizona Territory.  A skirmish outside of Confederate Arizona's capital of Mesilla between a confederate party and local pro-Union New Mexican guerrillas resisting the Confederate foraging expedition, resulted in a United States victory. Various accounts report from seven to twelve Confederates killed, including their commander Capt. Cleaver of the 7th Texas Infantry and as many as 40 of the local guerrillas.

The arrival of the advance party of the California Column on the west bank of the Rio Grande on July 4, 1862, prompted the rebel army to begin withdrawal to Franklin and then San Antonio three days later, covered by Herbert's Battalion of Arizona Cavalry acting as rearguard.
