Trying to find information on battles and area served in for the 15th Calvary Battalion.

This is what I know:
North Carolina 15th. Calvary Battalion
Formed in 1863
Companies: 4
Counties: Pasquotank, Chowan & Perquimons
Served in N.C. and Southern Va.
Disbanded in Chowan County in May, 1865
Office in Charge: Lt. Col. James M Wynn

Any information on Henry Patrick Sykes would also be appreciated.

Thanks in advance.
