On the morning of the 1st of May, the commander at Baton Rouge was startled by the intelligence of the close proximity of Grierson’s cavalry, and sent out two companies under Captain Godfrey, to meet and welcome them. The troops entered the city at three o’clock in the afternoon, amid cheers and shouts of welcome that rent the air, and echoed along the hills toward Port Hudson. Thus in less than sixteen days this heroic cavalry force had marched over six hundred miles, over marshes and rivers, endangering their lives for whole days at every mile they traversed. The last twenty-eight hours’ march was performed without either rest or food to men or horses. The loss to Colonel Grierson’s command during the whole journey was three killed, seven wounded, five sick and left upon the route, and nine men missing. Of the enemy, over one hundred were killed and wounded; five hundred taken prisoners (many of them officers); from fifty to sixty miles of railroad and telegraph wire destroyed, and three thousand stand of arms, together with army stores and government property, captured and destroyed—making in all a loss to the rebels of over three million dollars. BATTLE OF RAYMOND, MISS. MAY 12, 1863. On Thursday, May 7th, General McPherson moved his corps to Rocky Spring, and his camp was occupied next day by General Sherman. On Saturday McPherson again moved to the eastward, to the village of Utica, crossing the road occupied by McClernand, and leaving the latter on his left. On Sunday morning McClernand marched to Five Mile creek, and encamped on the south bank at noon, on account of broken bridges, which were repaired the same day. Monday morning Sherman’s corps came up, passed McClernand’s, and encamped that night at the village of Auburn, about ten miles south of Edwards’ Station, on the railroad from Vicksburg to Jackson. As soon as it passed, McClernand’s corps followed a few miles, and then took a road going obliquely to the left, leading to Hall’s Ferry, on the Big Black river. Thus, on Monday evening General McClernand was at Hall’s Ferry; General Sherman was at Auburn, six or eight miles to the northeast, and General McPherson was about eight miles still further to the northeast, a few miles north of Utica. The whole formed an immense line of battle, Sherman’s corps being in the centre, with those of McPherson and McClernand forming the right and left wings. From Grand Gulf the army marched westward, but, by these last movements, swung on the left as a pivot, and fronted nearly northward. [Illustration: UNION HEROES MARCY. HARNEY. MITCHELL. MILROY.
