Peter was strongly against slavery and joined the Missouri Home Guard Infantry, 14th Regiment, Company E, in Lexington, Missouri, 6 July 1861, for a three year period. His Missouri Home Guard unit supported the Union Army, but received very little income, equipment or training. His unit was composed mostly of German non-English speaking immigrants with the purpose of supporting anti-slave advocates in the community.
When Peter enlisted in the Missouri Home Guard, Anna and Peter had four children:
Henry - age 7
Mary - age 5
Amelia - age 3
Emma - new born
The Battle of Lexington began 18 September 1861, near Peter's property in the Anderson Addition. The citizens were cheering the Confederate troops as they approached Lexington, hoping the Confederate Army would regain control from the Union Army. In the Battle of Lexington, there were 15,000 Confederate troops and 3,500 Union troops, including Peter Westerhaus and his Missouri Home Guard unit. Confederate troops used hemp bales as shields, and pushed the bales forward as they advanced toward the Union troops for their final charge 20 September 1861. Union troops surrendered at noon, 20 September 1861, with very few causalities.
