To Shqype: your tree shows a little knowledge of Baltic languages - baltic has nothing to do with slavian. And here look at these trees: http://www.danshort.com/ie/iesatem_c.shtml http://www.danshort.com/ie/iecentum_c.shtml ofcourse to say which language is older in that tree is imposible, but it gives a normal knowledge how languages evolved. And I'm afraid, that in 1892 J. Wackernagel even didn't imagined, that there exist such language like Lithuanian (or that there exists such Baltic branch - as i writtten before - Russia (in 18641904) tried strongly to destroy this language - so your scientist was without even proper information). P.s. as for specific lithuanian unit it's hard to give any idea, but it's clear, that we didn't have a real knight unit - even in 1410 heavy cavalry used was polish, we got only a light cavalry. So for about 200 years most battles against better equiped enemies were fought in forests, where mounted units losed their advantages (and in that case: lithuanian swordsman got better chances than german knight).
