Question: Which battle of the Hundred Years' War is the subject of Leslie Barringer's historical novel?
Context: The Second Hundred Years' War (c. 1689 - c. 1815) is a periodization or historical era term used by some historians to describe the series of military conflicts between Great Britain and France that occurred from about 1689 (or some say 1714) to 1815.  The Second Hundred Years' War is named after the Hundred Years War, when the England-France rivalry began in the 14th century.  The term appears to have been coined by J. R. Seeley in his influential work "The Expansion of England: Two Courses of Lectures" (1883). Joris of the Rock is a fantasy novel by Leslie Barringer, the second book in his three volume Neustrian Cycle.  It is set around the fourteenth century in an alternate medieval France called Neustria (historically an early division of the Frankish kingdom).  The book was first published in the United Kingdom by Heinemann in 1928; an American edition followed from Doubleday in 1929.  Its significance was recognized by its republication by the Newcastle Publishing Company as the ninth volume of the celebrated Newcastle Forgotten Fantasy Library series in September, 1976.  The Newcastle edition was reprinted by Borgo Press in 1980 and 2010. Know Ye Not Agincourt?  by Leslie Barringer is a historical novel set in fifteenth century England and France.  It concerns the adventures of an English squire and his friends, their taking part in the month-long Siege of Harfleur and the Battle of Agincourt, and its bitter consequences for all of them.  It ends with a brief and unknowing meeting with the young Joan of Arc.  The book was published by Nelson in 1936 and has not been republished since.  Although written for younger readers, it exhibits some of the high literary quality of the Neustrian trilogy. Leslie Barringer (1895–1968) was an English editor and author of historical novels and historical fantasy novels, best known for the latter. The Battle of Agincourt ( ; in French, Azincourt ] ) was a battle of the Hundred Years' War that resulted in a English victory.  The battle took place on 25 October 1415 (Saint Crispin's Day) in the County of Saint-Pol, Artois, some 40 km south of Calais (now Azincourt in northern France).

Shy Leopardess is a fantasy novel by Leslie Barringer, the third and last book in his three volume Neustrian Cycle.

Shetland literature reflects the history of Shetland: five hundred years of Norse rule, followed by five hundred years of Scottish and British - this, in very simple terms, is the political reality of the last millennium.  Before the Norse, millennia of mysterious peoples and an immediately precedent Christian Celtic period; prior to and into the British age, three hundred years of Hanseatic trade with "Dutchies" (usually Dutch, sometimes, Germans).  All of these aspects of history have inspired and influenced Shetland's writers - just as the unchanging landscape of the 'Auld Rock', its weather, seasons, its flora and fauna, have provided a touchstone in the midst of sometimes tumultuous change; as the land itself is refuge from that other great favourite subject - the sea. Gerfalcon is a fantasy novel by Leslie Barringer, the first book in his three volume Neustrian Cycle.  It is set around the fourteenth century in an alternate medieval France called Neustria (historically an early division of the Frankish kingdom).

Its significance was recognized by its republication in 1973 by Tom Stacey in the UK and in March, 1976 by the Newcastle Publishing Company in the US, as the seventh volume of its celebrated Newcastle Forgotten Fantasy Library series.  This Newcastle edition was reprinted twice, once by Newcastle itself in 1977 and once by Borgo Press in 1980.
