This solution greatly exceeded Britain's psychological expectations, Talleyrand was almost explicitly indicating that as long as Britain supported Belgium's independence and geographically lifted the encirclement surrounding France, France wouldn't mind if Belgium's new government was pro-British.
Such a tempting offer, Duke Wellington and Viscount Palmerston, of course, agreed immediately, as they could not think of any reason to refuse.
And as Britain turned to support France, realizing that this conference might become a protracted tug-of-war, Russia's stance obviously loosened, which essentially confirmed that Arthur's intelligence was reliable.
And Talleyrand's concessions also implied that the vague reports about France that Arthur handed in this morning had no issues.
For a temporary organization without any appropriations, a young man of twenty to accomplish such great deeds, it was no wonder that Duke Wellington appreciated him.
