Barrett Point Barrett Point coastal fort is located at the foot of Mount Hayes at the entrance to Prince Rupert Harbour at History . The city of Prince Rupert was the nearest railhead to the Alaska and was strategically important to the defence of Alaska and West Coast of Canada . Barrett point battery was the key component of the defences of Prince Rupert in World War II . In 1938 Major Treatt of the Canada War Department , inspected the West Coast of Canada and determined suitable locations for Coastal defences . Barrett Point became the focal point of the defences that included gun batteries at Fredrick Pt , Casey Pt , Fairview Pt and Dundas Pt . The fort had 3 gun positions which were first equipped with Mk 12 6 ” anti - aircraft guns on Mk 7 mounts , later replaced by 3x 6 ” Mk 24 guns two on Mk5 mounts and one on a Mk5 mount . In addition a 6 pounder Hotchkiss quick firing gun was mounted , as well as 2x 40mm Bofors anti - aircraft guns . The guns of this fort and the others were controlled by a director station behind and above the centre gun position . Ammunition was stored in an underground magazine accessed by an electrical hoist for each gun . Behind the main battery protected by the hill was hardened generator room and other support buildings . Two searchlight towers front the fort along the shoreline . Bearings from these lights would be fed to the director for fire control . An observation post was established above the fort on top of Mt Hayes . The guns were manned by the Northern British Columbia heavy battery , Royal Canadian Artillery , later designated the 102nd Coast Battery of the 17th North British Columbia Coast Regiment . It ’ s unclear as to when the battery ceased operations , as war progressed and the threat of attacked diminished , the soldiers manning the defences were drawn down to serve elsewhere . It would appear the guns were removed some time between Sept 1945 and the end of 1946 . The last Coastal defences along the West Coast of Canada at Fort Rodd hill were disbanded in 1958 . Today . Much of the Battery fortifications are overgrown but can be seen on foot . Caution is advised as there are unmarked openings and entering the bunker should only be done with the proper equipment .

The establishment of an American Sub - Port of Embarkation with extensive docking facilities at Price Rupert , and a large staging camp at Port Edward , on the mainland ten miles by road and rail from the city , intensified Washington ' s concern about the security of the area , particularly having in mind the limited range of the " Interim " counter - bombardment 6 - inch battery at Fort Barrett . Early in 1942 the United States made available , to supplement the Barrett battery , two more 8 - inch railway guns , similar to those already installed at Christopher Point . On arrival at Prince Rupert the guns were run out to Fairview Point on spurs hurriedly built from the main CNR line , and were solidily braced on positions under which vast quantities of rock had been sunk into the muskeg . Much of the work of constructing roads , bridges and railway spurs in preparation for the big guns was done by members o the 9th Heavy Battery RCA , who had been manning mobile 8 - inch howitzers at Porter ' s Lake near Halifax . Arriving at Fairview on 26 March 1942 , they took up temporary residence in refitted railway cars near their new home , and by 9 April they reported the guns capable of firing in an emergency . When the Japanese attacked the Aleutians on 3 June , both guns wwere still in the process of being settled in their new positions . Late next day , however , No 2 gun was ready for action .

Two US 8 - inch M1888 railway guns with associated ammunition and fire control cars , became operational in early June 1942 . One 20mm LAA and 2 40mm LAA guns . The battery was built on a rail spur off the CNR mainline . The guns were left mounted on the railway cars and had 360 deg arcs of fire . Both guns were ready for action in early June 1942 . Digby Island to the west masked the battery ' s view of the open water to Chatham Sound , so Fairview was not fitted with search lights , being designated a ' day fort ' . It had two horizontal base lines of 5 , 000 yards each and employed a Whistler - Hearn plotting board . The battery was removed from an operational role April 28 , 1945 .
