We know that the five decoy sites at Haslingden, Accrington, Burnley, Worsthorne and Hambledon Hill were to protect Accrington according to Colin Dobinson's 'Fields of Deception' book. But we think they were specifically to protect the huge Howard & Bulloughs factory.
According to Wikipedia: "Bulloughs was one of the country's largest manufacturers. At its peak the Globe Works dominated the town, employing almost 6000 workers and covering 52 acres (21 ha).
During the Second World War they turned to manufacture of armaments such as bayonets, shells, gun carriages, mine sinkers and aircraft components."

Little of the huge factory survives today. Much of what does now houses Council departments.
According to the book 'Images of East Lancashire' by the Lancashire Evening Telegraph: "At its peak, the factory employed 8,000 - on war work." Which is 2000 more than Wikipedia says. The above photos is from the 1960's.
In his book 'Accrington Pals Trail', William Turner states that in 1914 "Over 4000 men and boys were employed, of whom quite a number enlisted in the Pals". Interestingly he goes on to say: "In September 1914 a large number of employees enlisted in the Pals. Some of these, however, were to return in 1915 as munitions workers."
