King Arthur and the Knights of the Round Table

Book four begins when ambassadors of Lucius, the Roman Emperor, showed up demanding Arthur pay tribute to Rome. Arthur refuses, and Lucius gathers his substantial forces to make war against England. Arthur and the Knights of the Round Table travel to meet Lucius’s forces, and eventually win the war. Arthur moves his army through Europe, surrounding towns and cities until he arrives in Rome and is crowed the new Roman Emperor. During the war while Arthur was moving his army thought Europe, Arthur killed a huge giant who lived on St. Michael's Mount. After returning from Rome many feast and tournaments were held in which Sir Lancelot gained more honor than any other knight of Arthur's court. This book tells the stories of the early adventures of Lancelot, including: his his escape from Morgan le Fay and the other three queens that were competing to be his lover; defeat of the powerful knight Sir Turquine who took his nephews Sir Lionel and Sir Hector; and many other tales. The book also tells us about Sir Lancelot’s love for Queen Guenever.
In Book Five a mysterious young man arrives in King Arthur’s court. Sir Kay teases the young man and calls him Beaumains. Beaumains stays at court for a year, and then is knighted by Sir Lancelot before going on a journey with a damsel named Linet. I don’t understand why the damsel was so angry that he was assigned the task of helping her. She came looking for help but didn’t want his help because he was a kitchen boy. This bothered me because it shouldn’t have mattered who helped her just that someone was willing to help. Beaumains says his name is Sir Gareth, the fourth son of King Lot and brother to Gawaine, Gaheris, and Agravaine. Gareth proves that he is a noble and worthy knight by killing the Black Knight and fought with the Green Knight, who in return of sparing his life allowed them to stay in his court to rest for the night. Gareth also defeats the Knight of the Red Lawns, who was holding Linet’s sister, the Dame Lioness by surrounding the castle. Gareth wins the hand of Lioness at a tournament hosted by King Arthur. Gareth and Lioness marry, and he is named one of the most powerful knights.
In book six it talks about the life and adventures of Sir Tristram. Tristram was born a prince of Lyonesse.
