Input: Consider Input: Question: What age was Robert I the year the Battle of Bannockburn occurred? Passage:Scottish field armies rarely managed to stand up to the usually larger and more professional armies produced by England, but they were used to good effect by Robert I of Scotland at the Battle of Bannockburn in 1314 to secure Scottish independence. He adopted a policy of slighting castles and made use of naval power to support his forces, beginning to develop a royal Scottish naval force. In the Late Middle Ages under the Stewart kings these forces were further augmented by specialist troops, particularly men-at-arms and archers, hired by bonds of manrent, similar to English indentures of the same period. New "livery and maintenance" castles were built to house these troops and castles began to be adapted to accommodate gunpowder weapons. The Stewarts also adopted major innovations in continental warfare, such as longer pikes, the extensive use of artillery, and they built up a formidable navy. However, one of the best armed and largest Scottish armies ever assembled still met with defeat at the hands of an English army at the Battle of Flodden in 1513, which saw the destruction of a large number of ordinary troops, a large section of the nobility and King James IV.

Input: Consider Input: Question: What century did the First Crusade occuring during? Passage:The widespread use of the swan as a badge largely derives from the legend of the Swan Knight, today most familiar from Richard Wagner's opera Lohengrin. A group of Old French chansons de geste called the Crusade cycle had associated the legend with the ancestors of Godfrey of Bouillon (d. 1100), the hero of the First Crusade. Although Godfrey had no legitimate issue, his family had many descendants among the aristocracy of Europe, many of whom made use of the swan in their heraldry or as a para-heraldic emblem. In England these included the important de Bohun family, which used the so-called Bohun swan as its heraldic badge; after the marriage in 1380 of Mary de Bohun (d. 1394) to the future King Henry IV of England, the swan became adopted by the House of Lancaster, who continued to use it for over a century. The swan with the crown and chain is especially associated with Lancastrian use; it echoes the crown and chain of Richard II's white hart, which he began to use as a livery badge from 1390. As well as several of his own white hart badges, Richard's treasure roll of 1397 also includes a swan badge with a gold chain, perhaps presented by one of his enemies mentioned above: "Item, a gold swan enamelled white with a little gold chain hanging around the neck, weighing 2 oz., value, 46s. 8d". He declared to Parliament that he had exchanged liveries with his uncles as a sign of amity at various moments of reconciliation.
