"we've dug tunnels to escape and found a country to give us asylum!"
"YEAH!!"
"Now let's kill every man inside the town without anyone noticing first!"
huh?!
If you wanted to get away then surely you should just start having people leave via the tunnels in the middle of the night then start the fire at 3 a.m. . Wjy try to do simultaneous massacre first where almost certainly at least one of the soldiers will escape the attempts of a girl to kill him with a knife and then manage to alert the guards ooutside the town walls?
