Due to the city gates being closed, even Philips, who was just on the opposite side of it, had no idea of the life and death battle his father was facing.
The marketplace was unfortunately too far from the place they had camped to allow even the sound of the raging fight to carry over, so instead, given the current time and being tired from the day's march, the prince and his entourage of more than 20,000 men were doing what was naturally expected of them- being blissfully asleep.
Only a few sentry were still up, guarding the place, but these men too failed to notice anything abnormal going on in the city as they were primarily on the lookout for only nearby enemies, not trying to see how their king was doing inside the city.
"*Yawnnn!* Those lucky bastards inside the city. I bet they are having the time of their life."
