- Chronicle of Hainaut, Gislebert of Mons (about 1195 to 1196). Ends in 1195, so it has no 1200 entries, but it is the indispensable background for Flanders and Hainaut: the career of Count Baldwin V of Hainaut (VIII of Flanders), his union of the two counties, the settlement with Philip over Artois, the rights, castles, fiefs and vassals of Hainaut listed by a man who ran its chancery, and the youth of Baldwin IX, who held both counties in 1200.

The Angevin houses' own annals of the succession crisis in their city: Arthur received at Angers in 1199 with Constance and the Breton and Angevin barons, John's counter-moves, the defection of William des Roches and the Angevin lords to John, and the peace of 1200 that left Arthur John's vassal.

For 1200 Wendover is mostly Howden rewritten, so he is a second witness only where he adds St Albans material: a long account of Hugh of Lincoln's last months, death and funeral, and anecdotes about John's conduct toward the Cistercians and his new queen.
