Otterburn was still negotiating for peace in London before the Battle of Pinkie. On Sunday 7 August 1547 he went to Hampton Court and met Edward VI of England. There he was dismissed as a diplomat by the council as it was now a time of hostility. He was given £75 as a gift for his departure. Otterburn saw, "afoir my eis verray gret preparatioun of weir, and actualie the gret hors, the harnes, the hagbutaris, and all gorgious reparrale set forwart towart our realme."&lt;br&gt;&lt;br&gt;Before my eyes very great preparation of war, and actually the great horse, the armour, the firearms, and all the gorgeous equipment set forward towards our realm. The "gorgeous" equipment included leather horse armour designed and made by the workshop of the Italian artist Nicholas Bellin of Modena. On Monday he returned to Hampton Court and had further discussions with the Protector Somerset. He wrote to Regent Arran urging him take his warnings of the English invasion seriously, and begged him to allow George Douglas of Pittendreich to negotiate with Somerset, writing; "I dreid ye will nocht gif credence quhill ye se thame cum in at the dur," (I dread you will not believe till you see them come in the door). Arran had already set up a system of coastal watchers and warning beacons. However, his army was defeated by the English at the battle of Pinkie on 10 September 1547.
