Send him all detachments of men that have come to join my army.

They can be so organized and officered as to be efficient, for they are nearly all old soldiers who have been detached or on furlough.

Until I pass the Santee, you can better use these detachments at Bull's Bay, Georgetown, etc.
I will instruct General McCallum, of the Railroad Department, to take his men up to Beaufort, North Carolina, and employ them on the road out.

I do not know that he can use them on any road here.

I did instruct him, while awaiting information from North Carolina, to have them build a good trestle-bridge across Port Royal ferry; but I now suppose the pontoon-bridge will do.
