English come when?

[Ice Rogue]

I've talked to Notradomus and says the English will come, what do I trigger to get them to come?

I've got no more useful active quests left, if its triggered by a quest could you tell me where to look? Thanks.

Welcome to GB, Ice Rogue.
You have to also complete the Crypt area, initiated by talking to Brother Michel in Montaillou, I believe. Once you do that, the English attack will begin.
