If you ever get the opportunity to visit the historical gem Quebec City, you’ll understand the folly of the American attack. The lower town is a maze of narrow streets flanked by stone buildings, with the fortress looming on the heights above. Montgomery and Arnold led their troops into a trap.
As I recall, Arnold actually came out a hero in this. Before he turned coat, Arnold showed himself to be a courageous and effective fighter.
