I found a reference to McGehee being involed in operations agaist shipping in the Mississippi River on Janury 6, 1863 and I found a After Action Report in his CSR where he advised Colonel Newton of this action.

JANUARY 6 Confederate troops captured and burned steamboat Jacob Musselman near Memphis. The com-mander of the Confederate company, Captain James H. McGehee, was acting under orders to reconnoiter the area, "burning cotton in that country and annoying the enemy on the Mississippi River" wherever possible. Attacks such as this emphasized the Union's reliance on naval control of the waterways to transport and convoy troops and supplies in areas already dominated by the North. Had this force afloat been weaker, the Confederacy might well have re-established vital positions in the west and elsewhere.
