I enclose a game where I have defeated all the Dragoons, Regulars and Artillery.
But the game continues, with no award of victory!

The only thing I can think of is that after I had wiped out most of the troops, the King captured an Indian village.
(By the way, that King's settlement didn't appear on the map, which was quite annoying! I enclose a snapshot of the game at that point too.)
When I finally realised what had happened, I captured the village, wiping out the last few troops. But the game wouldn't end...
