Still, as their intentions remain perfectly honorable, they continue the journey to Cornwall, and, in spite of all he suffers, Tristram delivers the reluctant bride into his uncle's hands.
Some legends claim that Iseult made her maid Brengwain take her place by the king's side on their wedding night, and that, although the Irish princess dwelt in the palace at Cornwall, she never proved untrue to her lover Tristram.

The romances now give us stolen interviews, temporary elopements, and hair-breadth escapes from all manner of dangers.

Once, for instance, Iseult is summoned by her husband to appear before the judges and clear herself from all suspicion of infidelity by taking a public oath in their presence.

By Iseult's directions, Tristram, disguised as a mendicant, carries her ashore from the boat, begging for a kiss as reward.

This enables the queen to swear truthfully that she has never been embraced by any man save King Mark and the mendicant who carried her ashore! Tristram--like Launcelot--deeply feels the baseness of his conduct toward his uncle and often tries to tear himself away, but the spell of the magic potion is too powerful to break.
