Tongera,
The description and narrative is good;don't you think that it would liven the picture if we knew the close associates of Manuel? the promising generals? Alexius' friends? army research for better effectiveness since it is in the process of reconquest? that was the general observation;
The campaign you are planning
lease Tongera,you didn't observe something odd? or odd movements? Look the map where is Ancara(or Ankyra) and look where is Ikonion;is it logical to take the army north,pass the level of Ancara,continue north to Constantinoupolis...for rest and triumph?
If the emperor needed a triumph he could have it with few troops to parade in the capital no need to march and fight raiders with the entire army for two months in order to return shortly;certain cavalry units and some infantry units would have sufficed.Heavy equipment and the bulk of the army should stay near Ikonion and be supplied from the port of Antalya.The emperor(or his staff that we don't know...) should take care for replacements and additional units for the campaign ande lead then south east later towards Ancara,and my question is this:what good besieging Ancara would do to the recovering of Anatolia? the Turks would know that Manuel with his army is marching towards Ancara and they would prepare(to the extend of their ability) accordingly which means delays in march from siege equipment,time lost in the siege of Ancara,increase losses from predictable moves etc.You can act though as Epameinondas or monsieur Vicompte De Tyrenne did:dominate your enemy on the open field and don't waste time in sieges;you would rather appear in the doorstep of the Turks unexpectedly like Alexander or Gaston de Foix,inflict a shuttering defeat and the cities will fall out of Panic,loss of will to fight or out of no choice.
Here if you like nutrualize Ancara,cut of its communications and supply and move on with a two-prong attack from south to north east and north to south east and chose your objectives.
Just a small help....
