Then Sir Tristram used daily and nightly to go to Queen Isoud when he might, and ever Sir Andred his cousin watched him night and day for to take him with La Beale Isoud. And so upon a night Sir Andred espied the hour and the time when Sir Tristram went to his lady. Then Sir Andred gat unto him twelve knights, and at midnight he set upon Sir Tristram secretly and suddenly and there Sir Tristram was taken naked abed with La Beale Isoud, and then was he bound hand and foot, and so was he kept until day. And then by the assent of King Mark, and of Sir Andred, and of some of the barons, Sir Tristram was led unto a chapel that stood upon the sea rocks, there for to take his judgment: and so he was led bounden with forty knights.
