Samuel F. Tappan was not a member of the Immortal 10, but he had several connections to that group. Mr. Tappan had been a newspaper reporter back east and came out in the same Emigrant party as Dr. Doy. He claimed 160 acres adjacent to Dr. Doy’s claim in the Wakarusa River Valley just south of Lawrence. He is quoted in a letter to Thomas Higginson (member of the Secret 6 who financed John Brown), “I am happy
to inform you that a certain Rail Road has been and is in full blast.” This letter can only be interpreted as talking about the Underground Railroad in Kansas. He wrote a letter on June 27, 1859 to Higginson and
reported on the Doy kidnapping and subsequent trial. This may have been an effort to get money to finance the rescue because the planning for the rescue was in progress and Tappen was in a position to have known of this rescue effort.
He reported for the New York Tribune and Boston Atlas about the fight between Border Ruffians and Abolitionists. He had one other connection to the Immortal 10. Mr. Tappan became Lt. Col. Tappan, 1st Colorado Calvary during the war. On November 29, 1864, Col. John Chivington, 1st Colorado Calvary, attacked and massacred a small band of peaceful Cheyenne at a place called Sand Creek. Capt. Silas Soule, of the Immortal 10, refused to order his unit to join in the massacre. He would later give testimony against Chivington and the presiding officer at that hearing was fellow abolitionist Lt. Col. Samuel F. Tappan. After testifying against Chivington, Capt. Silas S. Soule was killed by Charles W. Squires, another of the Colorado volunteers, presumably for his testimony. Chivington himself had been a Kansas Abolitionist before the War.
