Lee; and travelling to the Pacific Coast via steamer. The 24 ink and wash drawings depict the front of the Alamo and the mission of La Conception, San Antonio; Mexican women making tortillas; breakfast on the march; the head of Las Morus River; officer's quarters at Ringgold Barracks, Fort Vancouver, and Fort Dalles; "Chenoweth, chief of Dog-River Indians, hung at Cascades"; and "Cut-Mouth John, friendly Cayuse Scout".
The diary and artwork are accompanied by a small collection of correspondence, documents, printed material and photographs gathered by Brown's family members that include photographs of Brown and a hospital ward in Louisville during the Civil War.
