Grant's army extended beyond the camps at Pittsburgh Landing. Lew Wallace's division lay about five miles away at Crump's Landing, while William Nelson's division from Don Carlos Buell's Army of the Ohio had reached Savannah. Grant knew that additional troops were approaching and arranged his artillery to support fallback positions. The river offered both a protected logistical base and heavy gunboat fire, factors that help explain his confidence under pressure.
