The implication is that if there's no good idea to overturn this situation, then stop fighting, go home, wash up, and sleep.
At least, from Reiger's perspective, on the side of the Round Table army, the only truly high-end combat powers are Matthew, who has been empowered by the spirit base of Elf Knight Galahad, and Pasival with his holy spear, plus perhaps the first generation Elf Knight Habettelot and Altoria who has rung the Pilgrimage Bell five times.
The rest, whether it's Da Vinci or Gareth, although one is a Servant and the other a prototype Round Table knight, their combat power isn't very high. They can handle ordinary elves, but threatening an Elf Knight is undoubtedly a pipe dream.
As for Alberon, not to mention, he's never even been seen on the battlefield.
When it comes to Matthew, Pasival, Habettelot, and Altoria, even their combined strength doesn't quite match up to Bagster, even if they join forces, it's still uncertain if they could defeat one Bagster.
