On Saturday afternoon, March 22, about a quarter-past two o’clock, the Federal advanced pickets on the Strasburg road discovered the rebel cavalry, under Colonel Ashby, about half a mile beyond them, reconnoitering the woods on both sides of the turnpike, and steadily advancing. The pickets consisted of a few men of the Fourteenth Indiana infantry at that point, and they fell back half a mile to the hamlet of Kernstown, four miles from Winchester. Steadily did the troopers advance as the Union men wheeled to aim and fire. The first volley sent many rebels reeling from their saddles, and threw the rest into confusion. Before they could be again rallied for a charge, the gallant little band of infantry was beyond their power, without having lost a man killed or wounded. General Shields hearing of the advance of the rebel cavalry, ordered four advanced companies of infantry to rally to the support of the pickets, and hold the rebels in check till he could move down the division. These companies were one from the Maryland First, one from the Twenty-eighth Pennsylvania, one from the Forty-sixth Pennsylvania, and one from the Twenty-eighth New York. Their regiments had marched away under General Williams.

A battery of artillery was also sent forward, and General Shields, after ordering out the division, rode to the front, accompanied by his staff. While engaged in directing the fire of the artillery, a shell from the rebel battery of four guns, which now began to play on them, burst near him, and a splinter from it struck him in the left arm, just above the elbow, fracturing the bone and creating a painful wound. But without heeding it he gave a fresh order to the artillery, and continued on the field till satisfied that all was right.

The Federal division began to arrive in force on the field towards dark; the rebels, perceiving this, did not push their advance, but halted about three miles from Winchester for the night, lighted their camp fires and bivouacked, while the opposing army lay between them and the town.

About ten o’clock on Sunday, reinforcements of five regiments of infantry and two batteries of artillery having arrived from Strasburg, under General Garnett, were welcomed by vociferous and prolonged cheers from their lines. The attack was not long delayed. The enemy advanced his army, which now consisted of sixteen regiments of infantry, numbering eleven thousand men; five batteries of artillery, with a total of twenty-eight field pieces, and three battalions of horse, under Ashby and Stewart. His line of battle extended about a mile on the right of the village of Kernstown, and a mile and three-quarters on the left of it. The village lay on the road between the rebel right and centre. There is a mud road branching from the turnpike a mile or so from Winchester to the right of the road going towards Strasburg. This road passed through the left of the enemy’s centre, and was one of their points of defence. Beyond that is a grove of trees, and farther on, a ridge of hills with a stone wall about breast-high running along its summit. This was the rebel line of offence and defence on the right of the Union line.

The most advanced regiment on the Union side was the Eighth Ohio, of General Tyler’s brigade. The rebels made a furious onslaught about half-past ten o’clock, A. M., on Thursday, with the intention of turning the right flank. The Ohio Eighth met them with a deadly fire of rifles. Five times did the enemy emerge from the woods and from behind their stone parapet with vastly superior numbers, and strive in vain to accomplish their object. The Union left wing, consisting of the Thirteenth Indiana, Seventh Ohio and a battery of the Fourth regular artillery, under Captain Jenks, had a feint made on it, while the real attack of the enemy was being directed against the Union right wing. The feint on the left was a heavy fire of artillery posted on both sides of the village and the turnpike, which, however, did trifling damage. The Union battery replied, silencing those of the enemy, though the firing was well maintained for a long time on both sides. The Union centre consisted of the Fourteenth Indiana, the Eighth and Sixty-seventh Ohio, and the Eighty-fourth Pennsylvania. Two artillery batteries belonging to the First Ohio artillery, and the cavalry, consisting of the First Michigan and First Ohio, were drawn up in the rear. The Union right wing was made up of the Fifth and Eighth Ohio regiments and a battery of the First Virginia regiment. The reserves consisted of the Twelfth Indiana, the Thirty-ninth Illinois and a squadron of the Michigan cavalry. General Shields was unable to appear on the field in person, and the command consequently devolved upon Acting Brigadier Kimble, who led the centre. The right was commanded by Acting Brigadier General Tyler, while Colonel Sullivan directed the operations on the left.

The battle raged along the whole line with great fury from eleven A. M. till half-past two P. M., when General Shields, who received accounts of the progress of the fight on his couch, ordered the right, where the contest raged the hottest, to charge upon the enemy. That was an awful charge. The left of the enemy prepared desperately to repel the gallant troops, but their rush was irresistible. Previous to this the Union line of battle had been somewhat changed. The Eighty-fourth Pennsylvania reinforced its right, and also a battery of artillery. The whole Union force now engaged was about six thousand men, while that of the enemy was at the lowest estimate eight thousand. The rebels had also changed their line, and extending both their wings, presented a concave front. They had reinforced their left wing, and the charge to be made by the Union right was all important in its consequences. On it, at three o’clock, depended the fate of the entire battle. Tyler led the charge, sword in hand. The rebels fired from the woods with artillery and small arms, while the Federals advanced against their murderous showers of lead and iron, returning few shots and reserving their fire.

SPLENDID CHARGE OF THE RIGHT WING, UNDER GENERAL TYLER.

Up to this time the armies had not been much nearer to each other than three hundred yards, unless in some few instances. The wood was soon cleared at the point of the bayonet, the Unionists discharging their pieces at twenty and even five yards distance from the rebels, and then dashing at them with the bayonet.

The rebels fought well. They contested the ground foot by foot, and marked every yard of their retreat with blood. They retired behind the stone wall, on the ridge, but the Unionists jumped over, and drove them in the greatest confusion and with fearful slaughter upon their centre. The panic was contagious. Kimble ordered a charge along the whole line, and for a short time the fighting was desperate. The roar of the cannon was no longer heard, unless in occasional bursts, but the rattle of musketry was more deafening than ever.
