The Defence of the Scottish Border
AbstractScotland's relations with her southern neighbour, England, were often bad, and for significant periods there was outright war between the two countries. In these circwnstances it might be expected that a system of defence would be developed, perhaps combining regular patrols, on land and sea, with physical barriers and strongholds. Administrative arrangements would surely be in place to allow large defence forces to be brought speedily to deal with any invasion in force. Curiously, such a comprehensive system of defence has not been suspected by historians or castle experts, nor does it immediately appear that the evidence for one has been missed.
