Now the site of St. Louis University and a Mid-Town cultural center known as Grand Center, the area once known as Lindell’s Grove was the camp site of the Missouri State Militia in May, 1861. On the 10th of May, regular U.S. troops and specially enrolled home guard units under command of Nathaniel Lyon precipitated a confrontation here. The Camp Jackson incident was the first military action in the Civil War involving organized infantry on both sides. The first Union officer to die in battle, Capt. Constantin Blandowski, received his mortal wound here.
