soon as possible, your views as to the manner in which you can best carry them out, and your plan of operations under them. The commanding general desires also to learn what force of infantry you consider necessary to co-operate with or aid you in starting and at what point it should be directed, and how long it should continue its operations in order to render its assistance effectual. General Kautz will be ordered to report to you, and his command will form part of your expedition. The commanding general desires the expedition to start not later than the 17th instant. I am instructed to say that in view of the reduced effective force of the corps, instead of leaving one of the regularly organized brigades for the purposes specified in the dispatch of this morning, the detachment now under Colonel Bryan's command may be left. Colonel Batchelder, acting chief quartermaster, is directed to send you to-morrow the implements procured for a former expedition.
