Johnston had various remaining military units scattered throughout his territory and retreating to the south to avoid being cut off. Johnston himself retreated with the force under his personal command, the Army of Central Kentucky, from the vicinity of Nashville. With Beauregard's help, Johnston decided to concentrate forces with those formerly under Polk and now already under Beauregard's command at the strategically located railroad crossroads of Corinth, Mississippi, which he reached by a circuitous route. Johnston kept the Union forces, now under the overall command of the ponderous Maj. Gen. Henry Halleck, confused and hesitant to move, allowing Johnston to reach his objective undetected. This delay allowed Jefferson Davis finally to send reinforcements from the garrisons of coastal cities and another highly rated but prickly general, Braxton Bragg, to help organize the western forces. Bragg at least calmed the nerves of Beauregard and Polk, who had become agitated by their apparent dire situation in the face of numerically superior forces, before Johnston's arrival on March 24, 1862.
