After Refusing to Build Artillery, I Gave the Enemy Country a Lifeline

The empire fell, but I did not surrender. He refused to build cannon and was sentenced to life-long hard labor. I took the prisoners and built a canal for the enemy country. The hatred of the country's subjugation is someone else's account, I only count the earthwork and flow rate. On the day the water cleared, I had no freedom. But the water in the canal will keep flowing.
