There’s little doubt Harold would have set out shortly after he heard the alarming news. Presumably he would have started the march with his housecarls, who were the closest to a standing army available—it has been suggested he had 3000 at hand. He is said to have gathered forces as he rode north, which again must have taken time for they had to be notified and given a chance to prepare themselves—then travel a distance to meet Harold on the march. We don’t know how big the English army was—somewhere between 8,000-15,000 men—but this is one big logistical task in an age when communication was slow and unreliable. Yes, Harold’s march to York was certainly noteworthy, but I don’t think he was a miracle worker! (Even historian Edward A. Freeman was not prepared to accept the five day forced-march saga.)
Cooler heads have sorted out a more reasonable scenario. Harald Hardrada met his first major resistance in Northumbria at Scarborough, which would have been probably the first week of September. Presumably someone would have ridden south at that point, to notify the king of the Viking raids. Meanwhile, we know Harold disbanded the fyrd on September 8 according to the A.S. Chronicle, because “the men’s provisions had run out, and no one could keep them there (on the south coast) any longer”. The timing would be such that Harold could have received the news about Hardrada shortly after he returned to London. He certainly needed some time to prepare for a new campaign and wait for his mounted thegns to come back. So it stands to reason that he might have started his march north some time between Sept. 12-16, which would have given him 9-13 days to reach Stamford Bridge. Undoubtedly he learned about Fulford along the way, which would have spurred him on to greater efforts.
On September 24, four days after the Battle at Fulford, Harold arrived at Tadcaster with his exhausted troops. This town was upriver from Riccall where Hardrada had spread out his 300 ships (beyond a fork where the Wharfe meets the Ouse). It is believed that the Northumbrians withdrew their little fleet to Tadcaster when the Norwegians approached, since they were no match for the invaders. Harold spent the night at Tadcaster and started early in the morning to York, approximately ten miles away. By now he probably learned of Hardrada’s arrangement to wait for hostages at Stamford Bridge. It goes far to suggest that the northerners accepted Harold as their rightful king, for no one sought to warn the Norwegians of the royal army’s approach.
York may have surrendered to Hardrada, but it was apparently lightly guarded by the Norwegians—if at all. Harold made an unhindered entry into the city, acclaimed by the grateful inhabitants who must have felt doubly relieved that they had not been plundered. He marched his army through York and continued east another eight miles to Stamford Bridge. This means his army covered 18 miles that day before engaging the enemy. No rest for the weary!
