The only odd thing I ever saw there was neat the 76th NY's monument, there was one clover plant at the base of that monument that was all 4 leaf clover leaves- the whole plant. Every single one on the plant had 4 leaves. It was kind of cool but probably had more to do with whatever fertilizers they used there than anything else. Still kind of cool.
76th:
"On the 1st day of July the 76th Regiment had the dear bought honor to be the advance regiment of the 1st Corps, and nobly did they preserve the honor thus confered upon them. After coming in sight of the town of Gettysburg, our column filed to the left of the town and was forming in line of battle upon an eminence beyond the Seminary. Before our troops were placed in position, the enemy opened upon us a destructive fire with Artillery and Infantry. The 76th being the advance of the Corps, of course were on the extreme right, and subject to the cross fire from the enemy, who had succeeded in flanking us. Our gallant boys now returned their fire with interest as the enemy arose from their cover in a wheat field and charged upon us, supposing we were raw militia, they advanced their line steadily firing as they came. Our officers and men were falling upon every side and it was evident that they meant to surround us by their superior numbers, (the eleventh Corps had not yet arrived,) as we were now completely flanked. At this junction the gallant Major Grover fell mortally wounded, and died in a few moments after. The command now devolved upon Capt. John E. Cook, a brave and efficient officer who by his gallantry has won imperishable laurels. Too much cannot be said in praise of all, both officers and men, and many brave deeds were done which will never see the pages of history. At this time orders came from Gen. Cutler for us to fall back to the cover of a piece of woods. Our line was now re-formed and out of 340 men and 25 officers who entered the engagement only 100 men and 7 officers remained, showing how very destructive was the fire to which we were subjected, as we could not have been exposed more than twenty minutes. We again advanced and occupied our old ground with our skirmishers, but what a sight met our view.-Between our line of skirmishers and our line of battle lay our brave and heroic comrads, many gone to that land from whence no traveller returns, some in the agonies of death, and many of the wounded who were able to raise upon an elbow, cheering us on with: "give it to them boys, never mind us."
After holding our ground for sometime, we were marched in an oblique direction to the right, and took a position upon an eminence where the enemy were again trying their favorite flanking movement with a large force. There is no doubt but that the gallant and heroic 1st corps were now holding in check Lee's entire army. We were here engaged in a very heavy musketry fire, and exposed to a terrible shelling. After expending our sixty rounds of ammunition which told with terrible effect upon the enemy and completely silenced their Infantry fire, we were relieved by fresh troops. From this position we were forced beyond the city to the heights around Cemetry Hill, where the noble army of the Potomac upon the soil of Pennsylvania fully demonstrated to the world the kind of material of which it is composed.
Time and space will not permit me to give any details of the remaining three days fighting, which completely vanquished the invaders.
Yours Respectfully, C. A. WATKINS.
1st Lieut. and Acting Adj't."
