It has been pointed out to me that, in the process of losing Armagh, the remaining Irish troops are eliminated. As vassals of the Scots, the Irish retain Armagh, but they will have to rebuild their army.
The Danes having passed, the Normans rode south from York to attack London. The English, perhaps having strayed out in the noonday sun too often, marched out to fight them in the open field. The Normans first stormed the small hillfort that the English had garrisoned and left their baggage in. The Normans slew the guards and looted the baggage, then fought back and forth, eventually killing off enough of the "small men" (skirmishers) that the few remaining English took to their heels. The Normans paraded into London and established their Duke as "King of All Britain". (2BUA-0, 4 Prestige for the Normans, the English lose 3 Sp, 1 Ps total, retain London, but become Norman vassals).
The English pass in their turn; it is now the turn of the Welsh.
