Through the depth of winter the army toiled "in ineffectual efforts," says Grant, "to reach high land above Vicksburg from which we could operate against that stronghold, and in making artificial waterways through which a fleet might pass, avoiding the batteries to the south of the town, in case the other efforts should fail." A wetter winter had never been known. The whole complicated network of bends and bayous, of creeks, streams, runs, and tributary rivers, was overflowing the few slimy trails through the spongy forest and threatening the neglected levees which still held back the encroaching waters. There was nothing to do, however, but to keep the men busy and the enemy confused by trying first one line and then another for two weary months. By April, writes Grant, "the waters of the Mississippi having receded sufficiently to make it possible to march an army across the peninsula opposite Vicksburg, I determined to adopt this course, and moved my advance to a point below the town." Meanwhile, far below, Farragut and Banks were at work round Port Hudson: Farragut to good effect; Banks as usual. On the fourteenth of March Farragut started up the river with seven men-of-war and wanted the troops to make a demonstration against Port Hudson from the rear while the fleet worked its way past the front. But, just as Farragut was weighing anchor, Banks, who had had ample time for preparation, sent word to say he was still five miles from Port Hudson. "He'd as well be at New Orleans," muttered Farragut, "for all the good he's doing us." Six of the vessels were lashed together in pairs, the heavier ones next the enemy, the lighter ones secured well aft so as to mask the fewest guns. This arrangement also gave each pair the advantage of having twin screws. Farragut's flagship, the _Hartford_, leading the line-ahead, suffered least from the dense smoke on that damp, calm, moonless night. But the others were soon groping blindly up the tortuous channel. The _Hartford_ herself took the ground for a critical moment. But, with her own screw going ahead and that of the _Albatross_ going astern, she drew clear and won through. Not so, however, the other five ships. Only the _Hartford_ and _Albatross_ reached the Red River. Yet even this was of great importance, as it completely cut off Port Hudson from all chance of relief. Farragut went on up the Mississippi to see Grant, destroying all riverside stores on the way. Grant was delighted, and, in the absence of Porter, who was up the Yazoo, sent Farragut an Ellet ram and some sorely needed coal.
