The following dispatch has just been received:

GLASGOW, July 21, 1864.

I have just arrived. Lieutenant Woodruff, First Missouri State Militia [Cavalry], was attacked by about 200 guerrillas at Arrow Rock last night. He fought them three-quarters of an hour, losing 3 men missing, and all his horses. He and his men are here. I shall take him to Frankfort. I have placed the garrison of Miami and Cambridge at Frankfort. I brought 120 men, under Captain Wyckoff, from Lexington, who marched from Miami, at 7 o'clock this morning, in pursuit of the rebels, 150 strong, under Todd, who passed at 5 p.m. yesterday five miles south of Miami on the gallop east. Captain Queen marched with fifty men from a point opposite Chicken Point and six miles below Waverly at 5 a.m. this morning for Marshall. Ferguson with eighty men I met at Waverly at 7 p.m. yesterday and ordered him to Marshall. I leave for Miami soon; will return early to-morrow morning. Thornton's band, 300 strong, were at Mandeville yesterday at 12 m., marching east. Citizens of Carroll County are armed and willing to defend themselves.
