We’ve got a good one this week thanks to our friends at the Cody Firearms Museum: John Johnston’s Hawken and Bowie knife. John Johnston was the real historical figure the movie “Jeremiah Johnson” was based upon. The real Johns(t)on, we now learn, didn’t kill Crow or eat their livers. Or we don’t think so anyway. There are lots of stories about Johnston (sometimes spelled Johnson) and it’s hard to separate truth from myth. We know he was born John Garrison in Little York, New Jersey in 1824. He went to sea, then later enlisted in and deserted from the Navy during his service in the war with Mexico. At some point he went west, where he fought Indians with the Army, trapped, traded, mined and sold whiskey and was a deputy sheriff. Johnston was big, tough and had a violent temper. Legends grew up around him.
