London: Ward & Downey, 1887; 280 pages. The Douglas manuscript and Archaeologia wording are separate references.
Quality phase 275: W. Douglas’s 1887 monograph is distinct from the anonymous United Service Magazine article sequence held as work 3762.
Quality phase 522: first-publication chronology reconciled to the verified United Service Magazine serialization of 1881 (edition 3911), which predates the 1887 Ward & Downey book manifestation.
Phase 580: William Douglas identified as a former private of the 10th Royal Hussars; the 1881 serialization and 1887 book remain distinct manifestations of one work.
