dikers and bricklayers. Finding enough workers proved difficult, and in some cases men had to be pressed into service unwillingly. Labour disputes broke out, with strikes over low pay at Deal in 1539 and at Guisnes in 1541; both were quickly suppressed by royal officials. Large amounts of raw materials were also needed for the work, including stone, timber and lead and many other supplies. Camber, for example, probably required over 500,000 bricks, Sandgate needed 44,000 tiles, while constructing a small blockhouse along the Thames was estimated by contemporaries to require of chalk just to enable the manufacture of the lime mortar. Some materials could be sourced locally, but coal was shipped from the north of England and prefabricated items were brought in from London. Most of the money for the first phase of Device works came from Henry's dissolution of the monasteries a few years before, and the revenues that flowed in from the Court of Augmentations and First Fruits and Tenths as a result. In addition, the dissolution had released ample supplies of building materials as the monastic buildings were pulled down, and much of this was recycled. Netley Castle, for example, was based on an old abbey and reused many of its stones, East Tilbury Blockhouse reused parts of St Margaret's Chantry, Calshot Castle took the lead from nearby Beaulieu Abbey, East and West Cowes castles stone from Beaulieu and Quarr, and Sandwich had the stone from the local Carmelite friary. Milton Blockhouse was constructed on land that had recently been confiscated from Milton Chantry. By the second phase of the programme, however, most of the money from the dissolution had been spent, and Henry instead had to borrow funds; government officials noted that at least £100,000 was needed for the work. Garrisons The garrisons of the Device Forts comprised relatively small teams of men who typically lived and worked in the fortifications. The garrisons would maintain and care for the buildings and their artillery during the long periods of peacetime and, in a crisis, would be supplemented by additional soldiers and the local militia. The size of the garrisons varied according to the fortification; Camber Castle had a garrison of 29, Walmer Castle 18, while the West Tilbury Blockhouse only held 9 men. The ordinary soldiers would have lived in relatively basic conditions, typically on the ground floor, with the captains of the fortifications occupying more
