While Van Dorn and Price were making their unsuccessful attack on Corinth on October 2nd, Falkner's regiment was detailed to cut the Mobile and Ohio Railroad north of the town to prevent Grant from sending reinforcements from Jackson, Tennessee. The only report concerning the Rangers' role in this operation is a Federal one to the effect that a body of Confederate cavalry, said by one of the natives to be Falkner's men commanded by Falkner himself, removed a rail at Ramer's Crossing north of Corinth before being driven off. It is clear, however, that the Rangers were among the cavalrymen who did so much damage to the railroad that McPherson's reinforcing division from Jackson had to leave the cars at Bethel, fifteen miles north of Corinth, and march the rest of the way to the battlefield on a very hot day. The late arrival of these reinforcements was probably a decisive factor in the failure of Rosecrans' pursuit of the defeated Van Dorn.
