At last a commander for my Poles. The commander figure is one of the Orion cossacks and the winged hussar is from the same manufacturer.
The current forces for the Polish/Lithuanian commonwealth, including cossacks are
3 units of Polish hussars
2 units of Lithuanian Pancerni
2 units of Registered Cossacks
3 units of Free Cossacks
2 units of Haiduks
Plus Cossack rabble, skirmishers and artillery.
Should be enough now to have a game against the Swedes
