Text and translation of important letters written by William Lord Hastings, king's lieutenant of Calais, during the first months of the international crisis that followed the death of Charles the Bold, duke of Burgundy, at Nancy in January 1477. A Franco-Burgundian war broke out and England wished to maintain diplomatic relations with both sides: Edward IV's sister, Margaret of York, was Charles the Bold's widow, but Edward also wished to keep the peace treaty he had concluded with Louis XI of France in 1475. The editor has provided a detailed introduction to the circumstances and the book has a full index and bibliography. The folding map (also used on the dust wrapper) is a contemporary map of the Calais region surviving in a late copy, here printed in full.
