Henry of Almain was the song of one of the wealthiest men in Europe who joined what?
Henry of Almain Henry of Almain (Anglo-Norman French: "Henri d'Almayne") (2 November 1235 – 13 March 1271) was the son of Richard, 1st Earl of Cornwall and his first wife Isabel Marshal. His surname is derived from a vowel shift in pronunciation of "d'Allemagne" (English: of Germany), so called by the elites of England because of his father's status as the elected German King of the Romans (the "King of Almayne").
Thomas West, 2nd Baron West Thomas West, 2nd Baron West (1391 or 1392 – c. 30 September 1416) succeeded as Baron West at the age of 14. In less than a year, he married Ida de Saint Amand, younger daughter and coheiress of Amaury de Saint Amand, 3rd Baron Saint Amand (1341–1402). He was knighted on the eve of Henry V's coronation. He fought at the Battle of Agincourt, and is listed on a pipe-roll with a retinue of 14 lancers and 40 archers. Afterwards, he was assigned to the garrison of Calais. Next year, the Earl of Warwick, who was Captain of Calais, sent out an expedition on 24 September 1416 to capture a Genoese carrack, since the Genoese were allies of France. Thomas West was mortally wounded putting on his armor before the battle; he was arming himself at the foot of the mast when one of the stones being hauled up to the catapults on the masthead slipped; but he survived long enough to die in England. (His wife died that same fall; either a little before him, or on 15 December.) The "Gesta Henrici Quinti" puns in describing the manner of his death, suggesting that he received the chief of all evils ("verticem mali") while pursuing the root of all evil ("radicem mali").
