Editing Cape Cod Canal (section)

===World War II===
During [[World War II]], shipping again used the canal to avoid U-boats patrolling offshore. It was protected by coastal artillery batteries at the [[Sagamore Hill Military Reservation]] at the northern entrance and the [[Butler Point Military Reservation]] at the southern entrance. The artillery was never fired in defense of the canal.<ref>{{cite web |url = http://www.northamericanforts.com/East/masouth.html#boston |title = Sagamore Hill Military Reservation |work = American Forts Network }}</ref><ref>{{cite web |url = http://www.northamericanforts.com/East/masouth.html#newbedford |title = Butler Point Military Reservation |work = American Forts Network }}</ref>

The [[Mystic Steamship Company]]'s collier SS ''[[USS Stephen R. Jones (ID-4526)|Stephen R. Jones]]'' was grounded and sank in the canal on June 28, 1942. Shipping was routed around Cape Cod, and the [[Liberty ship]] SS ''[[SS Alexander Macomb|Alexander Macomb]]'' was torpedoed by the German submarine [[German submarine U-215|''U-215'']] on July 3 with the loss of ten lives. The canal reopened on July 31 after the wrecked ''Stephen R. Jones'' was removed with the help of 17 tons of dynamite.<ref>{{harvp|Reid|1965|pp=89–90}}.</ref>
