A.J. Smith's force arrived at Alexandria on March 20, 1864, intending to rendezvous with Banks's forces, under the immediate command of Franklin. However, Franklin did not arrive at Alexandria until March 25, 1864, and Banks himself, travelling separately from his troops, did not arrive at Alexandria until March 26, 1864. Banks' failure to arrive in a timely manner for his rendezvous with Smith was the first of many logistical miscues that caused much acrimony between Banks and his subordinates during the campaign. While he waited for Banks to arrive, Smith sent Brigadier General Joseph Mower on a successful mission to capture much of Taylor's cavalry and his outpost upriver from Alexandria at Henderson's Hill on March 21. Nearly 250 Confederates and a four-gun artillery battery were captured without a shot being fired.
