I am trying to understand where Roberts/Wiggins Battery was during the Kentucky Campaign.

Sifakis indicates that the battery was assigned to Liddell's Brigade of Buckner's Division in July to October 1862, but then indicates that the unit was presen for the Battle of Corinth, 3-4 October 1862.

These can't both be right and I haven't found the battery in the Order of Battle for Cornith or Perryville.

When did Wiggins join Forrest command? Skifakis indicates October 1862, after the Kentucky Campain, but is hat correct?
