A long while ago i paid tribute to General Subedei(Subotai), arguabley the best Mongol General and today i will post a tribute to another great General only this time he was not of Mongol.
Mongols this and Mongols that, yes i give credit where its due, but within the Mongol empire and officers were not always of Mongols, they were spread out from people who defected or saved and bought to work for the Mongol Khan empire.
The Mongol/Khan empire could not have done it without outside help.
