Why did Benedict Arnold go bad? Find out as Jim Bach, one of New Canaan’s favorite historians, presents American Betrayal, the saga of a turncoat, at the New Canaan Museum & Historical Society on March 29 at 4 pm. Bach’s presentation takes a look at the many events and personal shortcomings that brought about Benedict Arnold’s ultimate treason.

You’ll hear how General George Washington, British Major Andre and our local hero Major Tallmadge had roles in what led to Arnold’s demise. All the events took place not too far from our border including Ridgefield, Norwalk, Croton, Tarrytown and West Point.

Refreshments will be served. The presentation is free to members and their guests, and $5 for all others. For more information, call (203) 966- 1776 or go to www.nchistory.org.
