Weary and hungered, and vexed at the loss of his friends, Sir Guy came
to a castle where he sought harbour for the night. Sir Amys of the
Mountain, who dwelt there, welcomed him with a good will, and hearing
his adventures, offered to raise an army of fifteen hundred men to help

fixed for the wedding, Sir Guy let down a rope to Thierry in his pit,
and having drawn him up, the two made all speed to the castle of Sir
Amys. There, getting equipped with arms and armour, they leaped to horse
