By 5:30 p.m., Averell, citing his exhausted men and horses, "deemed it proper to withdraw." He left two Confederate officers who had been wounded and captured by Averell's troops, a sack of coffee, and the following message: "Dear Fitz, Here's your coffee. Here's your visit. How do you like it?" Some of his fellow officers believed that he lost his nerve, concerned about the presence of Jeb Stuart on the battlefield and, hearing the sound of railroad cars approaching, imagining the possibility of a Confederate infantry force pinning him against the river. The Union advance had covered 2 miles over more than 12 hours and resulted in 78 casualties (6 killed, 50 wounded, 22 missing). The Confederates lost 133 (11 dead, 88 wounded, 34 captured); 71 Confederate horses were killed and 12 were captured. The loss of the youthful Pelham, age 24, well respected by Robert E. Lee, Stuart, and many veterans of the Battle of Fredericksburg, was a shock. Stuart wrote after the battle, "The gallant Pelham—so noble, so true—will be mourned by the nation."
