7/3/2010:
Fort Lincoln was authorized in 1896, and in 1902, it was built just southeast of Bismarck. Later, it would memorably serve as an internment camp, but for many years, it served as a military post, and was watched and washed by soldiers living there.
On this date in 1916, preparations for July Fourth were well underway, and to look their best, the soldiers had a big uniform wash day. Imagine a platoon of men, handkerchiefs tied around their head, sporting their white BVDs, washing up their uniforms in an armada of small, square wash tubs.
The Bismarck Tribune reported they were on "undress parade" for most of the day.
