An efficient fleet of gunboats had been ordered to act in conjunction with McClellan’s forces in the reduction of Yorktown; but the presence of the Merrimac no doubt frustrated their plans. On the 15th of April several of the gunboats commenced shelling the woods below Gloucester. One boat approaching within two miles of Yorktown, brought her guns to bear on that place, until driven off by the rebel batteries.

About the same time a portion of the Potomac flotilla ascended the Rappahannock, meeting with but slight opposition, visiting the towns of Urbana and Tappahannock, and destroying the enemy’s batteries and huts at Lowry’s Point.

BATTLE OF LEE’S MILLS, VA.

April 16, 1862.

The defence of Yorktown prompted the rebel chiefs to project a line of batteries and earthworks across the peninsula which has been rendered so prominent in historic interest by the series of important events that have occurred between Richmond and Fortress Monroe. In the course of completing this line, a battery was commenced at a point on the Warwick road, on the estate of Mrs. Garrow, between Lee’s Mills and Winn’s Mills. There is here an extensive field, with woods to the right and left, and in the rear of the road. In front, at the foot of a gradually descending slope, is a branch of the Warwick river. The stream had been dammed up between these mills, the water covering a breadth of from thirty to forty rods, and in the deepest parts about four and a half feet deep. On the bank was a rifle-pit, and above it, on the hill, breastworks, with their embrasures for guns, frowned upon the water.

The arrest of this work, and the expulsion of the rebels, became necessary, in order to prevent the completion of what might have become a formidable obstacle. Accordingly, on the morning of the 16th, a party of skirmishers from the Fourth Vermont was thrown out, and took a position near the enemy’s one gun battery, at the point named, a New York battery being also advanced at the same time. Opposite the enemy’s works at that place there was a considerable space clear of large wood, overgrown with low shrubs and young pine, and surrounded in every direction except towards the enemy by a dense forest. Warwick Creek—from four to five feet deep and about twenty rods wide—separated this field from the rebel battery. Through the low shrubs and young pine the Vermonters made their way up to the edge of the stream, and poured upon the enemy a storm of rifle shot that he soon found it impossible to withstand. After a few moments of this fire not a man was to be seen within the enemy’s lines.

Two pieces of the battery—ten-pound Parrots, under Lieutenant Flynn—then took up a position in the edge of the wood, at one thousand yards from the enemy’s line, and opened fire. Then the enemy came bravely up to the business, and responded with the large gun in his one gun battery, and with two others in a battery behind it. Lieutenant Stewart, with the second section of the same battery—two twelve-pound Napoleon guns—was ordered up, with the left section, under Lieutenant O’Donald. With this reinforcement the fire became heavy between the artillery on both sides; the Union skirmishers and numbers of the enemy’s skirmishers also pouring in their fire whenever they saw an opportunity.

At about ten A. M., after nearly two hours’ sharp firing, the enemy ceased to respond, not, it was thought, because his guns had been disabled, but because the Union riflemen held his position so entirely under fire that it was almost certain death for his men to be seen.

It was now deemed necessary to ascertain the enemy’s force at this point and his disposition to fight. Upon consultation between General McClellan and two division commanders, it was determined to make a more decided demonstration of attack, and, accordingly, between three and four P. M., three batteries were ordered forward into the exposed field, and opened fire at about five hundred yards. This woke the enemy up; he responded warmly for twenty minutes, and once more relapsed into silence. In no way deceived by this, the three batteries continued to play upon his position for some minutes longer, when word was brought to the General of the Vermont brigade that the creek was easily fordable, at some distance to the right, and Colonel Hyde, in command of four companies of the Vermont Third, who had skirmished in advance, was ordered to send two of his companies across the creek at the point where it was said to be only knee-deep, advance them to the enemy’s left, and charge the work in rear. He accordingly sent across companies D and F, and supported them very closely with companies E and K. Meanwhile the Federal batteries became silent. No sooner were the Vermonters in the stream than the water was found to be much deeper than had been stated; the men went up to their arm-pits, and every charge of their ammunition, was, of course, thoroughly soaked. This attempt was made below the dam, and the enemy, when he saw their intention to cross, let in more water upon them by a floodgate.

While the men were in the stream, a large body of the enemy, estimated at three regiments, opened upon them from a rifle-pit on the bank, and this terrible fire cut down nearly half their number. Never was a fire received with greater steadiness or more glorious intrepidity. Except the poor fellows who had been killed or wounded, not a man of the magnificent Vermonters wavered, but all pushed on, and with one shout leaped to the bank, rushed upon the enemy with their bayonets, and fairly drove them in utter rout and confusion. But the contest was too unequal. No supports were within proper distance; and though the enemy was driven away from the first line of pits, and the other two companies of the Third were in the water to cross, those on the other side were ordered to retreat.
