Lambegus
Loyal servant of Sir Tristram who rode to rescue Queen Isoud.
Sir Lambegus is attested in Le Morte d'Arthur as a loyal servant and knight in the Tristram cycle. He identified himself plainly: "I am his servant, and my name is Sir Lambegus" (Le Morte d'Arthur, Book VIII, Chapter XXX). When Queen Isoud was demanded by Palamides, Sir Lambegus armed himself and "rode after as fast as he might" to rescue her (Le Morte d'Arthur, Book VIII, Chapter XXX). King Mark acknowledged his service, declaring "as I live, Sir Lambegus, I shall deserve it" (Le Morte d'Arthur, Book VIII, Chapter XXX).
Lambegus is later named among Sir Tristram's men -- alongside Gouvernail and Sir Sentraille de Lushon -- who sought their master after a crisis (Le Morte d'Arthur, Book VIII, Chapter XXXV).
The four citations from Le Morte d'Arthur present Lambegus consistently as a figure of service rather than individual adventure. His identity is established through his relationship to his lord -- he is Tristram's servant before he is anything else (Le Morte d'Arthur, Book VIII, Chapter XXX). His sole independent action, riding after Isoud, is motivated by loyalty to the household rather than personal quest. Even King Mark's acknowledgment frames Lambegus as someone whose value lies in what he provides to others (Le Morte d'Arthur, Book VIII, Chapter XXX).
