I checked the spelling mistakes myself.

Can you see if the tenses are ok? Thank you.

1)Arthur said that was where Christ’s blood had been kept after he had been crucified. Two knights soon declared the wanted to look for the Grail for one year and one day.
2) In 537 Arthur had to go to distant lands to fight. He asked a knight named Mordred to rule his land until he returned because he knew he was a loyal man. However, Mordred told everyone that Arthur was killed in the war, in France.
3) When King Arthur heard the news, he got furious and fought a long battle against Mordred.
4) Though King Arthur managed to kill Mordred with his spear, he was in turn mortally wounded by Mordred’s sword which went through Arthur’s helmet and hit Arthur’s head.
5) When Arthur was on the point of dying, he called Sir Bedivere and ordered him to bring his sword Excalibur back to the Lady of the Lake. 6) As requested, Sir Bedivere went to the lake and threw the sword far into the water.
7)On Sir Bedivere’s return, Arthur thanked him and asked to be carried to the lake. Sir Bedivere obeyed and put him in a boat.
8) Though his servant tried to dissuade him from leaving he replied that he was going to Avalon because his life was near the end.

1. the wanted = they

The tenses are fine.
