WW2 comes to Casco Bay
The United States entered the war  after the Japanese attack on  Pearl Harbor, December 7, 1941. The next day, the old coast defense guns at Fort Williams in Cape Elizabeth, Casco Bay, Maine were test fired.  The concussion of the firing blew the doors out of four recently constructed garages near the battery. The Coast Artillery quickly moved out its mobile artillery to  Biddeford Pool  and  Popham Beach to temporarily extend the defenses of the harbor. By April 1942,  the  US Navy installed anti-submarine nets and  highly secret anti-submarine indicator loops at all the entrances to the harbor (the indicator loop technology was developed by  the  Royal Navy  in WWI and modified by the USN in the 1930s to suit local needs).  The Coast  Artillery  planted  mine  fields in the main channels into Portland Harbor.  Coast Guard patroled the waterfront,  and  troops were sent to  Maine to  guard vital highway and railroad bridges,  such  as  the  Grand Trunk Railroad bridge  at  Yarmouth Junction.   The Navy was a popular  branch  of the service in Maine,  and a mass enlistment in Navy took place in Portland June 7, 1942.
