We sit in the middle of their navy: our guns can destroy any of their boats. But I forgot something: they have limitless numbers of flying men!
They approach like a swarm of locusts. No matter how many we kill, they will keep coming: it only takes one touch of a poisoned spear is deadly!
And are we even in the right? This was a peaceful land when we arrived. These soldiers are innocent volunteers, we can't just shoot them forever. Should we retreat away from the flying men and shoot their ships? Or should we give up this endless killing and let the other side win? Or do something else?
