Benedict Arnold's Betrayal
Benedict Arnold has been threatened by hoodlums, but Congress has denied him a military guard force. His wife, Peggy, is frightened so she contacts the one guy who kept her safe when the British occupied Philadelphia: Major John Andre, the head of British Intelligence. Major Andre can also do her husband some good so Benedict Arnold is now selling military information to the British. When Arnold is given the command of West Point, he decides to hand over the fort to the British along with General George Washington and Colonel Alexander Hamilton for the sum of 20,000 pounds or about $3.5 million in modern dollars. Arnold meets John Andre to finalize the plans, but then he can't get back to his ship. Arnold gives him maps of West Point and arranges for him to get back to the British side by land. All seems well, but as Washington and Hamilton ride up, a message arrives for Arnold. Major Andre was caught by a random patrol. They found the maps of West Point in his boot and he seems to have misplaced his uniform. That makes him a spy caught on the battlefield! Benedict Arnold pauses to speak to Peggy. He then excuses himself. Peggy is panicking. Benedict is running. Peggy starts screaming about how Washington has come to murder her child. It is not clear if she is just buying time for her husband to escape. If she is faking, she has big brass... uh... she stalls and Benedict Arnold gets away. She convinces them that she knew nothing about the conspiracy so she avoids the hangman's noose. But she knew plenty. 
The War Goes South
A strange darkness has fallen over New England. Could it be Judgement Day? The British forces decide to pack it in, get back on their ships and sail away... to Charleston, South Carolina. General Sir Henry Clinton has moved 14,000 troops and General Washington must decide what to do about it. Luckily, French support ships arrive at Rhode Island. Washington is listening carefully to his French advisors, but he doesn't like what he is hearing. The war is going to have to move south. Why is this such a tough decision? Well... according to historian Joseph Ellis, as the British troops are loading up to sail to South Carolina, 60 Massachusetts Militiamen have not been paid and many haven't eaten in 4 days. Their shoes are falling apart... at least the half that still have shoes. General Washington has ordered the confiscation of grain and cattle. He says it is either plunder or starve. He is writing to Congress in very plain language (for him). He tells them that he can't run a war with 13 separate war policies. Congress must find a way to impose a single policy and then fund it. He is making the case for a strong central government, but that won't come until much later. Soon Washington will lean on General Greene to head south and see what he can do. This Revolution is looking like a forlorn hope at this point.

Beacon Press. “After lunch, Arnold, Franks, and Lamb barged south to meet Washington at Smith's house near Haverstraw and accompany him to Peekskill. During their trip across the river, the commander-in-chief mentioned that he planned to come back up the Hudson on Saturday, September 23, to tour West Point and spend the night at the Robinson's with Arnold and Peggy. Privately, Arnold welcomed that information, key news to forward to the British to obtain his reward of £20,000.”

Half the men had no shoes, but were intending to walk home because they had long since eaten their horses. Down in New Jersey, where the countryside had been picked clean after four years of foraging, Washington was forced to order a general confiscation of cattle and grain from the local farmers, noting that the choice was between stealing or starving: "We must assume the odious character of plunderers instead of the protectors of the people."”

The primary cause of the event is believed to have been a combination of smoke from forest fires, a thick fog, and cloud cover. The darkness was so complete that candles were required from noon on. It did not disperse until the middle of the next night.”
