On September 17, 1176, at the Battle of Myriokephalon,the Byzantines failed to recover Anatolia from Turkish rule. From the article:
"Manuel decided, in consequence, that a strategy to eradicate the Seljuk power would pay the best results in the short-term, and began preparations for a major expedition aimed at Ikonion, the Seljuk capital itself. It is debatable whether, had his strategy paid off and he had been able to defeat the Seljuks and take the city, the policy could have worked in the long term, in view of the firm hold the Turks had by now established in the region. Nevertheless, having re-fortified a number of fortresses which directly challenged Seljuk power, war broke out and Manuel’s army, accompanied by a large siege and baggage train – stretching, according to the emperor himself in a letter he later wrote to Henry II of England, along ten miles of the route – set out in the summer of 1176 to confront the Seljuk leader in what, it was hoped, would be a decisive encounter."
