We remained in our position a while longer and saw many wounded men and stragglers making their way to the rear. Presently larger bodies of broken regiments appeared and we realized that the Fifth Corps was being forced back by the overwhelming numbers of the enemy. Some loud cheering on the high ground about a quarter of a mile to the rear startled us, and, from the appearance of the troops of which some regiments wore straw hats, we thought they were Rebels who had broken into our ranks from the rear, but they proved to be parts of French's and Meagher's Irish brigades which had been sent to reinforce General Porter. They were sent too late, however, to be of material assistance.
It was nearly sunset when two officers from General Sykes's staff made their appearance and gave some order to Captain John S. Poland who was now in command, and immediately the order was given to fall in, then by the left flank forward at double quick. The two aides-de-camp were mounted and led the column to make a charge on the enemy by General Sykes's order; one of them was Lieutenant Thomas D. Parker of my regiment, the name of the other, who belonged to a different regiment, I do not remember. We rushed on for about two hundred yards when we halted for a brief space to correct the alignment on the colors in the center; then the command "forward, charge." was given and we rushed up a hill for a hundred yards or so, cheering and yelling like mad, the two aides-de-camp riding in front in the center waving their swords.
It suddenly came to me that we were about to attack the enemy with bayonets. I had been instructed in bayonet drill and had practised until I was considered proficient; but I think at this moment I had a secret wish that the adversary whom I might encounter would not be a bigger man than I. I looked ahead but could see no enemy until we reached the crest of the hill, when we suddenly received a staggering fire, from a Rebel regiment that seemed not more than twenty yards away. I saw both of the mounted officers fall at the first fire, Lieutenant Parker being killed and the other wounded. One of the horses dropped, while the other rushed madly through our ranks.
I do not know whether it was by word of command or by instinct that we halted and instantly began firing instead of rushing on with the bayonet. I dropped on one knee and commenced firing as fast as I could; I aimed at their colors which were almost opposite ours. We were so close together that for a few minutes I could plainly distinguish the features and color of clothing of our opponents until the smoke obscured them. Suddenly their fire slackened and then ceased altogether; they seemed to have melted away down their side of the hill, and we could see only their dead and wounded on the ground where they had been in line. Why we did not pursue the retreating enemy puzzled me, for I thought we now had a chance to give them a good thrashing.
I stood up and looked around on a sight still vividly impressed on my memory. We were on high ground overlooking a considerable part of the fields on which the battle now raged; the sun was setting and with its almost horizontal rays lit up a magnificent panorama such as I have never seen since. I could see masses of infantry engaged in deadly struggle, the flashing of the artillery, and I heard the terrific roar; but what fascinated me was the figure of a Rebel officer, mounted on a horse reared up until he seemed to stand almost straight on his hind legs. I could see the officer waving his sword over his head, apparently urging his command forward. At this moment the horse and rider, illuminated by the parting rays of the sun, appeared gigantic and towered above all else. It was a picture for an artist. I took all this in, it seemed to me, in a few seconds, when I heard a command given and dropped back into my place. The enemy had been so close to us, and I had been so busy loading and firing, that I had looked neither to the right nor to the left, but now I observed that we had suffered severely and that two corporals of the color guard had been wounded.
Suddenly we heard the Rebel yell and saw a mass of Rebel infantry rushing toward us. We began firing at them as soon as we saw their heads appear above the crest of the hill. They halted, short of their former line it seemed to me, and delivered their fire as we had done when we had rushed at them. Later on, when I had time to think it over, it seemed to me that these tactics were not in accordance with what I had supposed a charge to be. In this case both sides, finding that the party attacked was not inclined to run, halted and peppered away at each other rather than become engaged at close quarters.
Our condition now was rather serious. Our ammunition was running very low and I suppose there were no reinforcements close at hand. A German battery posted on some high ground behind us tried to aid by firing at the Rebels, but unfortunately their aim was bad and they did us more harm than they did to the enemy; a few of our men on the right being killed and some wounded in the back by the firing of this battery.
I had not fired many shots in the second encounter on the hill and was in the act of ramming a cartridge, when a command or shout caused me to look to the right and I saw that our right wing had broken and were running down the hill helter-skelter, and that we were being fired at from that direction, as well as from the front. I understood that we had been out-flanked and that we would be taken prisoners. I yelled to my comrades of the color guard and started to run with them, not taking time to withdraw the ramrod from the barrel of my gun. There was a friendly piece of woods a hundred yards or more ahead of us to our right—a shelter we were all striving for, but which many did not reach for the enemy kept up a hot fire all the way. Twice I had to jump over men who had been hit and rolled over in my path. The enemy kept on firing volleys into the woods for a time but made no attempt to follow us. I got behind a tree and, like many others, fired off half a dozen cartridges in the enemy's direction, retaining but two out of the sixty I had during the day. Darkness was coming on. For us the Battle of Gaines's Mill was over, but it still raged on other parts of the field as long as it was light, and I think it was nine o'clock before all firing ceased. I learned later that our last attack had been made on Turkey Hill, not very far from the position we had held at noon before the battle began. Therefore we had lost little ground.
Efforts were now made by our officers to reform our command which had become scattered throughout the woods; and with difficulty the remnants were gathered together and we made our way out of the woods to the road by which we had approached in the forenoon. Here we reformed ranks and took up our march in retreat.
We soon came to a place where the road was skirted by thick woods on the left and a high bank on the right with a free space between the bank and the road on which were piled hundreds of boxes of infantry and artillery ammunition. As we passed, a young and very indiscreet officer made frantic appeals to some of us to stop and help him set fire to the ammunition to prevent it from falling into the hands of the enemy. No attention was paid to him further than calling him a fool, for the road was crowded with retreating troops and wounded men making their way painfully to the rear. An explosion of the ammunition would have made sad havoc among them.
