They just wanted to entrust their hopes to others

When soldiers were taken prisoners, all of their usable weapons would definitely be taken away as well. In other words, the Pyro Company soldiers were truly unarmed.

Meanwhile, the enemy they were facing was the expeditionary army who might not be defeatable even if they were armed.

At the beginning, these soldiers did not entirely resist capture. In the Pyro Company, there was nothing shameful about being held captive by the enemy. What they should do was to preserve their strength and wait for an opportunity to strike back.

Although their goal was to keep humanity's flame alive in the Central Plains, it did not mean they had to fearlessly charge at the enemy and sacrifice themselves. If the expeditionary army used them for hard labor later, they would still have a good chance of making themselves useful again.
