This page “Mount Up!”: Cavalry Operations in the Gettysburg Campaign has a good account of the Union Cavalry during the battle.

All three newly minted Brigadier Generals see action - George Custer, Elon Farnsworth, and Wesley Merritt.

Farnsworth is killed in a charge.

"Lost Triumph" is pretty good as well, if focused on the 3rd Day. Speculative (highly so), but the overall impact it suggests of what happened on East Cavalry Field is plausible.
