TYLER, June 17, 1864.

General J. B. MAGRUDER, Galveston:

Your dispatch received. General Boggs sent me a verbal message that probably 1,000 prisoners would be ordered to Alexandria for exchange, and half the rest would go to Hempstead and half remain at Tyler. With those going toward Hempstead a strong guard should be sent- from 300 to 500 men. Transportation her is insufficient. not a wagon to spare. I must impress teams to-morrow to keep up subsistence.

T. SCOTT ANDERSON,

Colonel, Commanding.
