The States of Holland sent their highest official, the Grand Pensionary Adriaan Pauw, to London in a last desperate attempt to prevent war, but in vain: English demands had become so extreme that no self-respecting state could meet them. War was declared by the English Parliament on 10 July 1652. The Dutch diplomats realised what was at stake: one of the departing ambassadors said, "The English are about to attack a mountain of gold; we are about to attack a mountain of iron." The Dutch Orangists were jubilant however; they expected that either victory or defeat would bring them to power.
