From Paris to Gottingen is about 400 miles, perhaps in the 21st century, taking a train would only take a day to arrive, but in the 19th century, a 400-mile land journey meant a kind of exhausting torment for both body and mind.
Although under the urging of the King, Arthur and his party were already going all out towards the Kingdom of Hanover, even the fastest horses in all of Paris paired with the most skillful coachman could only travel 40 miles a day, so it meant that Arthur and the others took a full ten days to enter the Kingdom of Hanover.
And to make time, the coachman took quite a few shortcuts along the way, and these roads were far less good than the main roads, so after several days of bumps, Arthur finally understood why Napoleon got hemorrhoids.
In fact, he even privately suspected that the Duke of Wellington, who had been marching for years, might also have this problem.
