David Macaulay has traced the step-by-step planning and construction of both castle and town from the hiring of a skilled master engineer to the actual test of castle defenses when hundreds of Welsh soldiers launch a direct atttack. Lord Kevin's castle, although imaginary, is based in concept, structural process, and physical appearance on several castles built to aid in the conquest of Wales between 1277 and 1305. The town of Aberwynern, also imaginary, is based in concept and physical appearance on towns founded in conjunction with castles in Wales during the same twenty-eight year period. This comination of castle and town in a military program displays both superior strategical skill and the farsightedness required for truly successful conquest.--Publisher.
