The mountain army had again begun its march on the afternoon of the third day of the month. Before starting the colonels summoned their men, told them the nature and danger of the service, and asked such as were unwilling to go farther to step to the rear; but not a man did so. Then Shelby made them a short speech, well adapted to such a levy. He told them when they encountered the enemy not to wait for the word of command, but each to "be his own officer," and do all he could, sheltering himself as far as possible, and not to throw away a chance; if they came on the British in the woods they were "to give them Indian play," and advance from tree to tree, pressing the enemy unceasingly. He ended by promising them that their officers would shrink from no danger, but would lead them everywhere, and, in their turn, they must be on the alert and obey orders. When they set out their uncertainty as to Ferguson's movements caused them to go slowly, their scouts sometimes skirmishing with lurking tories. They reached the mouth of Cane Creek, near Gilbert Town, on October 4th. With the partisans that had joined them they then numbered fifteen hundred men. McDowell left them at this point to go to Gates with the request for the appointment of a general to command them. [Footnote: Gates MSS. (in New York Hist. Soc.). It is possible that Campbell was not chosen chief commander until this time; Ensign Robert Campbell's account (MSS. in Tenn. Hist. Soc.) explicitly states this to be the case. The Shelby MS. and the official report make the date the 1st or 2d. One letter in the Gates MSS. has apparently escaped all notice from historians and investigators; it is the document which McDowell bore with him to Gates. It is dated "Oct. 4th, 1780, near Gilbert town," and is signed by Cleavland, Shelby, Sevier, Campbell, Andrew Hampton, and J. Winston. It begins: "We have collected at this place 1500 good men drawn from the counties of Surrey, Wilkes, Burk, Washington, and Sullivan counties (_sic_) in this State and Washington County in Virginia." It says that they expect to be joined in a few days by Clark of Ga. and Williams of S. C. with one thousand men (in reality Clark, who had nearly six hundred troops, never met them); asks for a general; says they have great need of ammunition, and remarks on the fact of their "troops being all militia, and but little acquainted with discipline." It was this document that gave the first impression to contemporaries that the battle was fought by fifteen hundred Americans. Thus General Davidson's letter of Oct. 10th to Gates, giving him the news of the victory, has served as a basis for most subsequent writers about the numbers. He got his particulars from one of Sumter's men, who was in the fight; but he evidently mixed them up in his mind, for he speaks of Williams, Lacey, and their companions as joining the others at Gilbert Town, instead of the Cowpens; makes the total number three
