The armies gathered at Towton were among the largest at the time. Contemporary sources (like "Gregory's Chronicle") claimed that the soldiers on each side numbered in the hundreds of thousands. These figures are thought to be exaggerated, and modern historians believe that a combined figure of 50,000–65,000 is more likely, between one and two percent of the English population at the time. An analysis of 50 skeletons found in mass graves between 1996 and 2003 showed most were 24 to 30 years old and many were veterans of previous engagements.
