Alonzo Silsby served in the 1st Ohio Light Artillery, Battery I, also known as Dilger’s Battery after its commander. According to Nancy West’s To Dwell with Fellow Clay, Silsby died of wounds received at the Battle of Gettysburg. I have visited both Silsby’s gravesite as well as the monument at Gettysburg that marks the general area where the Battery took up position. Silby’s greatly eroded original tombstone does seem to mention the battle specifically, but he also has a newer government-issue monument.
