For a long time I also thought the 157th NY pitched into Doles' further north, as their monument and advance marker on the Carlisle road indicate. However, it was impossible for me to mesh that scenario with accounts from Krzy. brigade. Pressure upon the latter's left flank (which can only have come from Doles) was described by Col. Willis of 119 NY and Maj. Ledig of 75 PA in their official reports,and also by Capt. Winkler of 26 WISC and Theodore Dodge of 119 NY. Dodge describes the Confederate line (Doles) advancing to within 80 yards, while the Federals on his right were in full retreat (from Gordon's attack). Krzy.' line was already being pushed back when Dodge was wounded and the Confederate battle line passed over him.
Everything points to Doles being fully preoccupied with the 157 NY
after attacking and pressing back Krzy.'s regiments. I can't see how it could be before, given the extant accounts, unless you give Gordon nearly all the credit for forcing Krzy. to retreat.
So that tells me the 157th could not have attacked as far north as their monument and advance marker state. Doles writes of being in pursuit of Krzy. when a strong force (157 NY) approached his right and rear. The other major piece of this puzzle involves the 21 GA. The latter regiment "fell down behind a fence" (per Cpl. Sidney Richardson of 21 GA) as the 157 NY moved into their front. Therefore I placed 21 GA behind the likeliest fence on my 3:30 p.m. map. This placement also appears to be fully corroborated by C. D. Grace of 4 GA, who mentions the 157 NY approaching in the low ground formed by a creek, as explained in:
Brig. Gen. George Doles left an intriguing description of his brigade's movements on the late afternoon of July 1. After having defeated the flank attack by the 157th New York, he writes of heading toward the Theological Seminary to assist his division's efforts against the Union First Corps...
