At Memphis, a key incident occurred which would darken Porter's reputation, and which his detractors see as part of a consistent behavioral pattern which put him and his men beyond the norms of warfare. According to the "History of Shelby County," which is generally sympathetic to Porter, "Most conceded that Col. Porter's purpose for capturing Memphis, MO. was to seize Dr. Wm. Aylward, a prominent Union man of the community." Aylward was captured during the day by Captain Tom Stacy's men and confined to a house. After rousing him overnight and removing him, ostensibly to see Porter, guards claimed that he escaped. However, witnesses reported hearing the sounds of a strangling, and his body was found the next day, with marks consistent with hanging or strangulation.
