The gun
that used to be on display in the museum, was a 40 millimetre BOFORS of 1957 vintage,
and was presented by the Ministry of Defence to the Old Comrades Association of the
15th (Isle of Man) Light Anti Aircraft Territorial Regiment of the
Royal Artillery for use as a museum piece. Weighing almost 5 tonnes, it was 25
feet long from Muzzle to tow bar and on its wheels in the towing position was 7
feet wide power control. Its ammunition, 40 millimetre, 2lb weight high
explosive shells were fused to explode on impact but to allow for mis-hitting a
target, can be set to self-destruct at either 11 or 17 seconds. With an opening
range of 2,000 yards, its rate of fire was 240 shells per minute at a muzzle
velocity of some 3,800 feet per second. It was, however, a much later development
than the Bofors gun of World War II as operated by the Manx Regiment – it was
in every sense a very much bigger and heavier piece of artillery than the
earlier war-time models.
During
World War II Bofors guns played a vital role and in the hands of the Manx
Regiment were operated not only as anti-aircraft weapons using the type of
ammunition described above, but also as anti-tank guns with armour-piercing
ammunition and in the final stages of the war in Europe, as enemy air attacks
decreased, as light artillery against enemy infantry concentrating before
counter attacks. These guns of World War II vintage, as shown above, with a rate
of fire of 120 shells per minute, were manned by detachments of 7 men, each of
whom was responsible for a specific duty. No. 1 was the detachment commander and
he was responsible for the tactical control, the selection and identification of
targets and was in command of the gun. Nos. 2 and 3 were the layers for line and
elevation, No.4 loaded and fired the gun, Nos.5 and 6 were responsible for
feeding ammunition to the loader and No.7 was the target spotter. Getting into
action and operatingthe gun was therefore essentially a team effort.
Armed with unprotected, manually operated and light-weight Bofors guns, the
Manx Regiment saw action prior to and during the Battle of Britain and, after
sailing from England in November 1940, experienced very active service overseas
in Egypt, the Island of Crete, Eritrea, the North African deserts from El
Alamein to Tunisia, Italy Via Salerno for the first front in occupied Europe,
and finally from the beaches of Normandy through France, Belgium, Holland to
North-West Germany until the war in Europe ended.
It is officially recorded that Bofors gun detachments of the Manx Regiment
accounted for some 300 enemy aircraft destroyed and with its lengthy record of
active service overseas, the Regiment is unrivalled by any other Light
Anti-Aircraft Regiment in the annals of the Royal Artillery.
