West Russian/Ruthenian/Lithuanian Cavalry 15th Century

[joewally1]

I am designing a scenario of the battle of Tannenberg/Grunwald/Zalgiris from 1410 and want to get the opinion of the forum if any of the mounted cavalry in the Lithuanian army could be classified as knights, similar to the Poles. I have the Later Lithuanian list from Eternal Empire and it gives the option for Polish knights. Would this troop type limited to Poles only or could some West Russian/Ruthenian Cavalry (I am thinking of the three banners from Smolensk led by Lengvenis) or if any of the Lithuanian Cavalry be classed as knights.

My thinking is based on the adoption of armour and the heavy war horse by the Lithuanians that began almost 200 years earlier after first contact with the Teutonic Order. I understand that all Lithuanian or Ruthenian cavalry would not be knights but perhaps one or two battlegroups could.

I was looking at the plates in the Osprey Russian Medieval Armies Book and read the narrative from the Osprey Hussite Wars Book that inluded Ruthenian/Lithuanian knights equipped in the standard Italian armour style.
