The narrative follows Geoffrey Lysle and his household from coastal Warblington through crossings to Normandy, local feuds at Taillemartel, ambushes, captivity, daring escapes, and maritime mishaps, joining wider campaigns that include the siege of Harfleur, the march of the outnumbered English force, and the confrontation at Agincourt. Alongside comrades such as Arnold Gripwell and Sir Oliver Lysle the story depicts skirmishes, acts of loyalty and treason, sieges, and the grim aftermath of battle, concluding with further operations in Normandy and the recovery of honours amid the upheavals of medieval warfare.
