A group of soldiers at the front line realizes everyone else is gone. Their “front” is lost, the other armies have fled or have been captured, and they are being encircled.
They have nowhere to go … but it will still take some time before the enemy reaches them. (It’s a long distance, they’re the last one in the row, it takes time to dispatch of the others, etc.)
And so they try the biggest possible gamble: they very quickly build farms/a town and pretend they are innocents just living there.
How is this written?
- Well, first chapter could be from the view of the enemy. Victorious, expecting to meet the final army here, but instead they meet … nothing. They enter a city that seems completely oblivious to the war, treats them as friends (not hostile at all), etc.
- This goes on for a few chapters, as they try to continue the war from here, while oddities and mysterious signs are piling up …
- Then we switch to the other side, which has all these funny and tense ways to prevent being found out. The enemy visits the town, some even claim a home, they start using it as a headquarter of operations in that area … while absolutely everyone in that town is actually a soldier trying to hide that.
- Maybe they got rid of all the weapons … but one man secretly kept them, thinking this was too much of a gamble.
- Maybe they realized it was weird to have 100% men living here, so they tried to give the few women in their squad a prominent position and make up silly “rules” as to why there were so few.
- Maybe they had to hide massive tanks—or other nearly un-hideable things—and came up with intricate buildings and “no entry zones; radiation” signs to keep people out.
