Roman Igorevich reconciled with his brother, Vladimir Igorevich, in early 1209 or 1210. Their united forces vanquished Benedict's army, expelling the Hungarians from Halych. Vladimir Igorevich sent one of his sons, Vsevolod Vladimirovich, "bearing gifts to the king in Hungary" to appease Andrew, according to the "Galician–Volhynian Chronicle". A group of discontented Hungarian lords offered the crown to Andrew's cousins, the sons of Andrew's uncle, Géza; they lived in "Greek land". However, the cousins' envoys were captured in Split in 1210. In the early 1210s, Andrew sent "an army of Saxons, Vlachs, Székelys and Pechenegs" commanded by Joachim, Count of Hermannstadt, (now Sibiu, Romania) to assist Boril of Bulgaria's fight against three rebellious Cuman chieftains. Around the same time, Hungarian troops occupied Belgrade and Barancs (now Braničevo, Serbia), which had been lost to Bulgaria under Emeric. Andrew's army defeated the Cumans at Vidin. Andrew granted the Barcaság (now Țara Bârsei, Romania) to the Teutonic Knights. The Knights were to defend the easternmost regions of the Kingdom of Hungary against the Cumans and encourage their conversion to Catholicism.
