The lead horse mentioned is Ksar d’Esprit, a full TB, who won all six puissances he entered in one year.
Elles, he’s one reason why I love Ksar/Herod line horses in sport so much.
He’s got both Herod lines, as well as a Matchem line through Barcaldine on the first page, along with a good bit of Saint Simon.
