In riding up, Hancock had not failed to notice--indeed, no one could--a wooded hill standing off at some distance to the right of Cemetery Hill, from which it was separated by a wide and deep hollow, yet at the same time joined by a ridge so low and narrow as to be hardly seen when looking down from above. This low, connecting ridge is several hundred yards in extent, and, forming as if does a natural parapet for infantry, was all that stood in the way of pushing a force through between Cemetery and Culp's Hill to the rear of the Union troops. Of the two hills it is enough to say that as Culp's Hill is much the higher, whoever held Culp's Hill would also hold the key to the Union position, as Hancock found it. [Sidenote: Ewell sees it too.] [Sidenote: But Hancock seizes it.] The enemy had not been slow to perceive this on his part, and while hesitating what to do Early had pointed it out to Ewell, his chief, who fully agreed with him that it should be seized as soon as Johnson's fresh division got up.[47] But while they were hesitating Hancock was sending what was left of Wadsworth's division, reinforced by the Seventh Indiana, with a battery, to occupy Culp's Hill; so that when Johnson's scouts went there after dark, instead of finding the hill unoccupied and undefended, they fell into the hands of Wadsworth's men. Meredith's worn but undaunted brigade dropped into position behind the narrow strip of ridge spoken of, a sure guaranty that no enemy would break through at that place. In this instance Hancock's eagle glance and no less prompt action undoubtedly saved the whole position, since if Ewell had succeeded in establishing himself on Culp's Hill, it would have taken the whole Union army to drive him out. [Sidenote: Hancock reports all safe.] Considered merely as a rallying point for broken troops, Cemetery Hill had now served its purpose. Hancock could now say to Meade, not that the position was the best they could have taken for disputing the enemy's progress, but that all was safe for the present, or equally in train for the withdrawal of the troops, should that be the decision. In a word, he would not commit himself unreservedly to a simple yes or no.[48] [Sidenote: Meade's Decision.]
