Pvt. Theodore Goldin
Carroll was the long-forgotten Missouri river port north of Lewiston.
When Howard's command reached Carroll on October 1, they found the steamer Benton waiting for them. The riverboat carried Howard and a detachment of seventeen men upstream to Cow Island.
The Benton was the biggest freight carrier on the upper Missouri. Between 1875 and 1887. It made 59 trips to Fort Benton or Cow Island depending on the water level the most of any boat.
