The greatest general of the Mongols was Subedei (also "Sabutai"; spellings vary); he was not a noble but was extremely well thought of within the ranks of the nation.
Thus Subedei and one of the sons of Genghis led a reconnaissance in force through central Asia and eastern Europe, a campaign which is now legendary.
So Subedei would divide his force into two parts, and would only send about one third of it (the forlorn hope) to attack the enemy where they were lined up, shivering with fear.
Subedei was, although he lacked Temuchin's persuasive powers and psychosocial prowess, a man of great and highly disciplined intelligence.
Subedei, the mastermind and real leader behind the illustrious European campaign of 1236-1242, laid waste the whole of Eastern Europe in the course of this theatre of operations.
Subedei was a native of the Urianqai tribe, whose geographical homeland is situated east of the Bajkal sea, in what are the present-day republics of Tuva and Buryatia.
