The Reason of the fight at Baker's Creek.
--The Jackson correspondent of the Mobile Advertiser writes the following reasons why the battle of Baker's Creek was fought by Pemberton:It has been frequently asked why was the battle of Baker's Creek fought? After the smoke of the conflict has cleared, and we have a full view of affairs, there are many Solomons to be found, and great Generals, at a safe distance, who criticise movements with a sang froid that is delightfully refreshing. These men daily plan huge campaigns, fight gigantic battles, in imagination, and "somehow or some where else"always gain glorious victories that eclipse the great captains of history, and they romantically see a grateful country and an applauding world kneeling in homage at their august feet. With these facts before me, I hope that I am not asking too much of the public when I humbly request them not to become of fended with your correspondent for modestly obtruding his views.
The enemy firmly located at Jackson, gave him the capital of the State, the command and possession of all Northern, Western and South western Mississippi, together with all the railroads in that portion of the State, except Vicksburg, therefore, Gen. Johnston would have been forced to organize his army in eastern Mississippi, at least from 80 to 100 miles from Vicksburg. By Pemberton's marching out of Vicksburg and assailing brant's rear, he compelled him, in self defence, to evacuate Jackson, and hasten to the protection of his rear and supplies, and so precipitate was his retreat that a battery which had been taken down to Pearl river, to batter down the pillars of the railroad bridge, was hastily spiked and the guns thrown into the river. These guns have since been fished up. Thus the enemy was compelled to relinquish all the advantages obtained by capturing Jackson, and hasten his attack on Vicksburg and his operations for the investment of the city, while Johnston took possession of Jackson and the railroads, organized his army, and is now within 30 miles of the Hill City, which is 44 miles west of Jackson. The enemy is unable to capture Vicksburg by assault. He is menaced now on both flank, from and rear, and will soon have too give up the siege or fight a battle under disadvantageous circumstances, and which he can only gain by the force of numbers and bulldog courage.
