Who was he and what unit did he serve in?
My research was not in vain - you were - William Scott was born in Groton, Vermont on the 6th of April in 1839 and was living a quiet life in this farming community when he "heard the call" from President Lincoln to "serve and preserve the union". He joined the 3rd Vermont Regiment, Company K, that congregated in St. Johnsbury, on the grounds of the Caledonia County Agricultural Society at "Camp Baxter".

From the Wikipedia article about the "Sleeping Sentinel":
"The Sleeping Sentinel is a 1914American black-and-white silent film that depicted PresidentAbraham Lincoln pardoning a military sentry who had been sentenced to die for sleeping while on duty. In the actual incident during the American Civil War, William Scott, a private in the 3rd Vermont Infantry, fell asleep while on guard duty. He subsequently was arrested, court-martialed, and sentenced to be shot. Lincoln heard about the case, pardoned Scott, and returned him to his unit. William Scott was actually standing before his firing squad when the death sentence and pardon were both read, however no one had told him that he had been pardoned. Scott later died at the Battle of Lee's Mills.
The "Sleeping Sentinel" was a melodramatic poem written about this case. In the film, Lincoln happens upon the scene while riding in a carriage, stopping the squad just before it fires (which never happened)"
