Early in the morning of April 17, 1863, volunteer brigade of union cavalrymen under the command of Col. Benjamin Grierson rode south from their headquarters just above the Mississippi border. 16 days, 600 miles, and a number of skirmishes later, the sixth and seventh Illinois cavalry regiments entered Baton Rouge in triumph having marched the entire length of the state of Mississippi. Such a bold cavalry thrust deep into Confederate territory had never been attempted before. Col. Grierson was on his own: he was simply told to harass the Confederates - thus diverting their attention from Grant, who was poised for attack on Vicksburg - and to sever the Vicksburg railroad. How he accomplish these objectives is skillfully told here in a day-by-day account of the raid: the long and grueling marches; the consternation of the Confederate commanders, whose intelligence reports were thrown off time and again by Grierson's bluffs and the tricks of his advanced scouts, the "Butternut Guerrillas"; the daring attack on the Vicksburg railroad; the tatterdemalion parade into Baton Rouge, with 300 fleeing slaves happily bringing up the rear. GRIERSON'S RAID does more than follow the fascinating twists and turns of the union force whose maneuvers so flabbergasted the Confederates, often with amusing results. The author has fashioned a smooth flowing narrative that also includes short biographies of the key men - notably, of course, Col. Grierson, a music teacher turned cavalrymen who heartily distrust of horses. [When he was a boy a horse kicked him in the face, leaving him blind for two weeks; he bore the scars for the rest of his life.] But Grierson's attitudes towards horses did not hinder his generalship. One reads this book with keen admiration for the brilliance of a tactician whose brazen raid anticipated the free wheeling thrusts of a Guderian or a Patton in World War II. Mr. Brown has been able to draw from unusually full sources in writing this book. In addition to official records and newspaper accounts, he has made use of a privately published record of services and a manuscript autobiography by Grierson, and the letters and journals of two other members of the brigade. -- Publisher.
