DUNN'S HILL, July 28, 1864.
What is the enemy's force of cavalry? What do you propose to do?
Are you directing operations?
R. E. LEE.
[JULY 28, 1864.]
General R. E. LEE:
I consider myself as directing operations as much as circumstances permit. I infer that the enemy's force of cavalry is formidable. General Anderson has been fighting it and General Gary has sent repeatedly for more troops. I have just returned from near our left. Pemberton has been ordered to Richmond and the right of my line is weak. The enemy have erected batteries in front of New Market and threaten along Four-Mile Run. I have not seen Anderson since late last night, who is on the left. I am about to return.
R. S. EWELL.
HEADQUARTERS, Dunn's Hill, July 28, 1864.
A division of cavalry is coming. Send a guide to pontoon at Drewry's to guide it to point where needed. Chambliss should be near there by this time.
