I live on The Sullivan Trail and have hunted it for 35 years, if you look up( Lossings Field Book of the Revolution vol. 1) you can see that Sullivan left almost all of his cannons at Fort Sullivan in what is now Sayre PA. after the Battle of Newtown, and none of the cannons were taken very far.
So if that web site says they had cannons with them,that is dead wrong,tell me y they had Gold with them to fight, this is just a wild story about the gold.
