Kennesaw Mountain saw the third time during the American Civil War in which William T. Sherman employed a direct assault upon entrenched Confederate positions.  The attack failed as much as his previous two attempts.  All through the Atlanta campaign, Sherman had gotten around the Confederate positions set out by Joseph E. Johnston through flanking maneuvers.  Sherman wrote to Washington, “The whole country is one vast fort, and Johnston must have at least 50 miles (80 km) of connected trenches with abatis and finished batteries. We gain ground daily, fighting all the time. … Our lines are now in close contact and the fighting incessant, with a good deal of artillery. As fast as we gain one position the enemy has another all ready. … Kennesaw … is the key to the whole country.”  For the key, Sherman decided to open it with a direct frontal assault.
