Despite outnumbering the pitched battles of the British Civil Wars of the 1640s, sieges, particularly 'small' sieges against single structures such as castles and country mansions, have not been subjected to the intensive study that the battles have enjoyed. While sieges are described in the contemporary literature, we do not fully-understand the physical dynamics of 17th century siege warfare, nor have we identified the key archaeological signatures of such military events. Although castle interiors have been 'cleared' and some partially excavated, the areas immediately beyond the walls have not come in for systematic study. Yet these 'siegefields' may be 'conflict sensitive' and hold the greatest potential for information regarding siege activity. Using an array of data drawn from various survey methodologies, it may be possible to establish strategies for examining siege sites.
