In "The Major Adams Story" it is explained that Seth Adams had commanded a militia group (apparently in Philadelphia) and they enlisted en masse in the Union Army in 1861, that Bill Hawks was Sergeant to Major Adams and that Wooster was a late enlistment as a private (in various episodes it's mentioned that their regiment was under Generals William Tecumseh Sherman and Ulysses S. Grant ). However, a different story in "The Colter Craven Story" (season 4), we are told that in 1860 Adams and Hawks were partners in a lumber enterprise in Galena, Illinois, and on the eve of the Civil War, Adams headed up the 2nd Illinois Volunteers - although without a bit of military knowledge - and was given guidance by old friend "Sam", then a resigned former captain and a civilian but subsequently General of the Army . Grant, who - encountering Adams again after the battle of Shiloh (April 1862) - gave him a battlefield promotion from Lieutenant to Major (in "The Colter Craven Story", Season 4, episode 9, broadcast November 23, 1960). In "The Willy Moran Story" it is mentioned that Major Adams fought in the Battle of Gettysburg.
I have heard that the color of tren comes down to a few factors. One of the factors could be the quality or age of the raw powder. Anoth factor can obviously be how the tren is made. Tren is a compound that will change colors when it becomes more oxidized. If you heat tren too long it will undergo more oxidation and therefor have a darker tint to it. Also if the raw is added to by hot oil this would cause much more rapid oxidation vs putting it in cooler oil and letting it slowly heat. I have not seen any proof that the oxidation will change the potency of tren though so the color really shouldn't effect it. Also the carrier oils would obviously change the overall color, as they come in different shades. Hope this helped
