Fort Pemberton was so little above the water that it was thought that a rise of two feet would drive the enemy out. In hope of enlisting the elements on our side, which had been so much against us up to this time, a second cut was made in the Mississippi levee, this time directly opposite Helena, or six miles above the former cut. It did not accomplish the desired result, and Ross, with his fleet, started back. On the 22d he met Quinby with a brigade at Yazoo Pass. Quinby was the senior of Ross, and assumed command. He was not satisfied with returning to his former position without seeing for himself whether anything could be accomplished. Accordingly Fort Pemberton was revisited by our troops; but an inspection was sufficient this time without an attack. Quinby, with his command, returned with but little delay. In the meantime I was much exercised for the safety of Ross, not knowing that Quinby had been able to join him. Reinforcements were of no use in a country covered with water, as they would have to remain on board of their transports. Relief had to come from another quarter. So I determined to get into the Yazoo below Fort Pemberton.
Steel's Bayou empties into the Yazoo River between Haines' Bluff and its mouth. It is narrow, very tortuous, and fringed with a very heavy growth of timber, but it is deep. It approaches to within one mile of the Mississippi at Eagle Bend, thirty miles above Young's Point. Steel's Bayou connects with Black Bayou, Black Bayou with Deer Creek, Deer Creek with Rolling Fork, Rolling Fork with the Big Sunflower River, and the Big Sunflower with the Yazoo River about ten miles above Haines' Bluff in a right line but probably twenty or twenty-five miles by the winding of the river. All these waterways are of about the same nature so far as navigation is concerned, until the Sunflower is reached; this affords free navigation.
Admiral Porter explored this waterway as far as Deer Creek on the 14th of March, and reported it navigable. On the next day he started with five gunboats and four mortar-boats. I went with him for some distance. The heavy overhanging timber retarded progress very much, as did also the short turns in so narrow a stream. The gunboats, however, ploughed their way through without other damage than to their appearance. The transports did not fare so well although they followed behind.
The road was somewhat cleared for them by the gunboats. In the evening I returned to headquarters to hurry up reinforcements.
Sherman went in person on the 16th, taking with him Stuart's division of the 15th corps. They took large river transports to Eagle Bend on the Mississippi, where they debarked and marched across to Steel's Bayou, where they re-embarked on the transports. The river steamers, with their tall smokestacks and light guards extending out, were so much impeded that the gunboats got far ahead. Porter, with his fleet, got within a few hundred yards of where the sailing would have been clear and free from the obstructions caused by felling trees into the water, when he encountered rebel sharp-shooters, and his progress was delayed by obstructions in his front. He could do nothing with gunboats against sharpshooters. The rebels, learning his route, had sent in about 4,000 men--many more than there were sailors in the fleet.
Sherman went back, at the request of the admiral, to clear out Black Bayou and to hurry up reinforcements, which were far behind. On the night of the 19th he received notice from the admiral that he had been attacked by sharp-shooters and was in imminent peril. Sherman at once returned through Black Bayou in a canoe, and passed on until he met a steamer, with the last of the reinforcements he had, coming up. They tried to force their way through Black Bayou with their steamer, but, finding it slow and tedious work, debarked and pushed forward on foot. It was night when they landed, and intensely dark. There was but a narrow strip of land above water, and that was grown up with underbrush or cane. The troops lighted their way through this with candles carried in their hands for a mile and a half, when they came to an open plantation. Here the troops rested until morning. They made twenty-one miles from this resting-place by noon the next day, and were in time to rescue the fleet. Porter had fully made up his mind to blow up the gunboats rather than have them fall into the hands of the enemy. More welcome visitors he probably never met than the "boys in blue" on this occasion. The vessels were backed out and returned to their rendezvous on the Mississippi; and thus ended in failure the fourth attempt to get in rear of Vicksburg.
