As I mentioned below, there was a Lunar eclipse on May 5 1110. That is what caused the Moon to be dimmer than the stars. Maximum eclipse was at 22:58 UT. England would have experienced the full eclipse.
"Nor was the moon being eclipsed by Earth's shadow "
But there was a Lunar eclipse on May 5 1100. That is what made the Moon dimmer than the stars.
