As Cadwallader Colden died in 1776, it's probably unlikely that he was involved in suborning Benedict Arnold who was an active soldier in the Patriot cause through 1777 and whose plan to hand over West Point was hatched in 1780. Perhaps the source is referring to CC's son, Cadwallader, Jr.? I have a cite for an article which I have not read which might shed some light on this: Joseph Bragdon, "Cadwallader Colden, 2nd, an Ulster County Tory," New York History, 14 (1933): 411-421.
