On July 5, seeking a way to cross the Chattahoochee River and gain access to Atlanta, Brigadier General Kenner Garrard's cavalry began the Union's twelve-day occupation of Roswell, which was undefended. The next day Garrard reported to Sherman that he had discovered the mills in full operation and had proceeded to destroy them, and that about 400 women had been employed in the mills. On July 7 Sherman replied that the destruction of the mills "meets my entire approval." He ordered that the owners and employees be arrested and charged with treason, elaborating, "I repeat my orders that you arrest all people, male and female, connected with those factories, no matter what the clamor, and let them foot it, under guard, to Marietta, whence I will send them by [railroad] cars, to the North. . . . Let them [the women] take along their children and clothing, providing they have a means of hauling or you can spare them."
