Buuxi weedhan soo socota: 1071, Catepanate ee Talyaaniga si weyn ayaa loo yareeyay, iyadoo kaliya ay ku harsan yihiin dhawr hay'adood iyo caasimadooda
waxaa go'doonsaday reer Norman. Sida laga soo xigtay "Anonymus Barensis", Romanos IV, oo ahaa boqorkii Byzantine ee xukunka hayey, wuxuu u diray labaatan markab oo uu hoggaaminayay Joscelin of Molfetta, oo ah kacdoonkii Norman, oo ay weheliyaan Pateranos, si ay uga xoreeyaan Bari. Si kastaba ha noqotee, Normaanku waxay soo qabteen oo ay ku kala firdhiyeen maraakiibta xeebaha Bari, waxayna qabsadeen markabkii watay Joscelin, in kasta oo Stephen uu awooday inuu gaaro magaalada. Stephen wuxuu ogaaday in difaaca magaaladu aysan macquul aheyn, wuxuuna u diray Argyritzos, oo ah nin ka tirsan dadka deegaanka, si uu u soo bandhigo nabadda. Normanku waxay aqbaleen nabad, Bari ayaana is dhiibtay.
