Henrici Quinti, Angliæ Regis, Gesta, is a first-hand account of the Agincourt Campaign, and subsequent events to his death in 1422. The author of the first part was a Chaplain in King Henry's retinue who was present from King Henry's departure at Southampton in 1415, at the siege of Harfleur, the battle of Agincourt, and the celebrations on King Henry's return to London. The second part, by another writer, relates the events that took place including the negotiations at Troye, Henry's marriage and his death in 1422.

Mathri Burlal Chamber is in Mathri, Pembrokeshire, Prehistoric Wales Neolithic Burials.
Archaeologia Cambrensis 1872 Pages 81-143. In Mathri (martyrs) parish are the remains of a large chamber [Mathri Burlal Chamber [Map]], consisting of a capstone 13 ft. long by 8 broad, resting on one low supporter, the whole partially buried in the hedge. This apparently is the one mentioned by Fenton, who gives the length 14 ft.; and states that it was supported by stones 4 ft. high on one side, and scarcely 3 on the other. He speaks also of a cistvaen at one end, which had lost one side and its cover. This may have been a small secondary chamber. Another cromlech, according to the Ordnance Map, ought to be near it; but no traces of it are now remaining, and it is to be recretted that Fenton does not even allude to it.
