In War of the Rebellion, Series 1, Vol. 14, I found this:
Pocotaligo, May 29, 1862.
DEAR GENERAL:

After a spirited engagement, which lasted two hours, we succeeded in driving the enemy from their cover, and the cavalry is in full pursuit. We have 2 killed and 5 wounded. I regret to say that Captain Parker is one of the killed. We will proceed at once to the railroad. The battery has just arrived. We should have some ambulances to bring our dead and wounded.
Yours respectfully,
B.C. Christ
Colonel Fifteith Pennsylvania Volunteers
