and equip such men of his remaining brigade as require it. In case any surplus remains, it will be reported to these headquarters tat it may be turned over to some other division.

III. The object of this order is to retain as many equipped and mounted men with this army as there are at present, including the Third Brigade, by mounting others before that command leaves. This requirement will be observed in the execution of this order.

IV. The batteries of horse artillery belonging to the Second Brigade (Tidball's), serving with corps, will be replaced by batteries from the First (or Robertson's) Brigade, after which Captain Tidball will report with his brigade to Brigadier-General Tyler, commanding Artillery Reserve.

V. To equalize the number of batteries in the brigade, the Ninth Michigan Battery is transferred to the Second Brigade Horse Artillery.
