Land for Fort Dearborne was acquired in two separate condemnation processes from private land owners. The first acquisition was for 206.08 acres formally acquired 11 May 1943 and the second was for 60 acres on 11 Oct 1943. The landowners were only given 30 days to vacate their property in 1942.

A temporary battery of four 155mm guns was placed at Odiorne's Point on concrete Panama mounts in 1942 while three new World War II gun batteries were under construction. The temporary 155mm battery was withdrawn as the new batteries came on line in 1944.
