The first time you sent an army into their land without permission, the friendly peace-loving Angles sent a respectable noble to politely ask you to leave. He was refused even admittance to your general. The captain of the guards even snatched a huge germ decorating the nobleman's cloak and kept it as his own. Some "hefty negotiation" ensued and the words "

the Noble High King of all Anglians" had been heard from one of your hotheaded guards. Your army passed through their territory and defeated the treacherous British rebels without many incidents, except some barn burning because the locals refused to cooperate without being paid.
Then there was a rebellion,
the Rebellion as recorded in the chronicles. Houses were burned, people massacred and a huge area depopulated. The Anglian King, too busy with his petty continental conflicts, scraped the bottom of his barrel to assemble a mercenary army and marched it hastily to save the British fiefdoms. Before this ragtag bunch of criminals ever hit the first nail building ships to cross the Narrow Sea, your mighty army, uninvited of course, appeared again and defeated the rebels. This time, marching on a desert of burned villages and salted fields, they needed a little bit more persuation to acquire enough food, often involving torture and hanging of peasants.
Now the Anglian High King faced a dilemma: he had promised the mercenaries rewards from the rebel's treasure and he couldn't pay them now. Worse still, other provinces in Southern England began to see you as their true protector, not he. Afterall, he had been ignored twice. There were also rumors that he was now a weakling controled by one of your agent from behind. Such affronting of the King's honour must not go unanswered. Heavy-hearted, he decided to go to war against his once friend (you), using the very same mercenary army he had assembled before.
But you, warming yourself behind your mighty castle wall, were oblivious of all these development. All you could see was a ungraceful warlord defying all of your goodwill gestures and choosing war instead. Such a irrational dumbhead! How could anyone who lacks even children's common sense become king? Or was that the Lord's (aka CA) will to punish you from your prosperity?
Sorry couldn't resist
