The Missouri State Militia was a federally funded state organization established in 1861 and early 1862 for the purpose of counteracting the guerrillas, and Confederate units that were doing recruiting in Missouri. The 2nd Battalion was organized between March and May of 1862 at Harrisonville and Kansas City and was in service for only about one year. Companies A, C and F were involved in the fight at Lone Jack. The 2nd Battalion was mustered out of service on March 31, 1863. For these reasons, the information on the men is limited.
Of those present at the battle whose origin is known, 19% were born in Missouri, while 16% were originally from Kentucky. 10% of the men were born in Indiana, while Illinois and Ohio were equally represented at 9%, with Tennessee nativity at 7.4%. Several other states were also represented, including one man born in Gettysburg, Pennsylvania. There were two men born in England and two from Ireland.
The most common first names were John and William at 9%, and these were followed closely by James and George at 6.7%. The average age of the men present in the fight was 26. The oldest man in the battle was Poncy (spelled Pouncey on his gravestone) A. Smith. He was almost age 63, born on December 18, 1799 in Kentucky. The youngest was Delbert Demo; he was age 15 when he enlisted.
Of those men present in the battle, 26% of the men died, from all causes, at some point during the war, including being killed at Lone Jack or dying of wounds received there. For most, the cause was a disease of some kind, but one accidentally killed himself. In the Battle of Lone Jack, the average age of the men who were killed outright or died of wounds was 28.
Many of the horses, almost all of which were owned by the men themselves, were lost, either killed or captured as a result of the fight at Lone Jack. The total value of those horses, based on the estimated value assigned to them prior to the battle, was $4,615.
After their service in the 2nd Battalion, many of the men went back to civilian life, while some volunteered in other units to serve out the war. Having survived his severe wounding at Lone Jack, one went back home to Ohio and enlisted in a regiment there. He was captured and died in a prison camp in Florence, South Carolina in 1864.
Based on the information I was able to find, the last two veterans of the companies which fought at Lone Jack were Delbert Demo of Company F and Albert Davidson Sturges of Company A. Delbert died April 1, 1926 at the age of 80 and Albert died on December 5, 1926 at the age of 84. Delbert was also the youngest of those at Lone Jack who served in the unit at the age of 15. Including those who died during the war and after the war, my research developed that 51% of the men are buried in Missouri, and 17% are buried in Kansas.
