Dorn was killed on 23 Dec. 1944 in Belgium. This collection holds materials for researchers interested in the 4-H program as well as the realities of parents grieving the loss of their only son. First Sgt. George Burchett, who had served under Captain Dorn, related the events surrounding Dorn's death in a letter to the parents of his late commanding officer. Dorn and three of his officers were in a house planning an attack on German-held Haugimont when they were attacked. "I went down to the house where Capt. Dorn was. He was lying in just inside the front door. He had died instantly.... five 88's had hit the house." Buried first in the Henri Chappelle Cemetery in Belgium, Olin Dorn, Jr., was re-interred in Sumter County, S.C., in 1947. His widow relinquished her rights as the next of kin and his mother began her mission of memorializing her son. In a letter to Special Information Section, Office of Technical Information, H[ead]q[uarters] Army Ground Forces, Washington, D.C., 2 Aug. 1947, Mrs. Dorn wrote, "...if there is any thing that you may, in the form of, records or history of my son, send me I shall be rewarded in a small measure for being robbed of my only heir."
