In June 1690, then, William of Orange finally arrived in Ulster as only a King could, viz. with three hundred ships, fifteen thousand troops, hundreds of thousands of pounds sterling, more Princes, Dukes, and Bishops than a boat-load of playing-cards and chess-sets, and a lot of Dutch artillery. He marched south, pausing at Dundalk long enough to collect the regiments that had wintered over there, and then invaded Leinster at the head of thirty-six thousand men. He made straight for Dublin, where James Stuart had established his rebel Parliament. King William had a wooden house, designed by one Christopher Wren—that same bloke who was building the new St. Paul’s in London. It was ingeniously made so that it could be taken down in sections at a few minutes’ notice, transported on wagons, and put back up again wherever William decided to establish his headquarters. Normally he erected it in the midst of his army, which was not at all usual for a campaigning King, and made a good impression on his soldiers.
