of his empresses were Franks) and at the beginning of his reign he is reported to have re-equipped and retrained his native Byzantine heavy cavalry along Western lines. It is inferred that Manuel introduced the couched lance technique, the close order charge at speed and increased the use of heavier armour. Manuel personally took part in knightly tournaments in the Western fashion; his considerable prowess impressed Western observers. Manuel organised his army in the Myriokephalon campaign as a number of 'divisions' each of which could act as small independent army. It has been argued that it was this organisation which allowed the greater part of his army to survive the ambush inflicted on it by the Seljuk Turks. Indeed, it was a stock of Byzantine writing to contrast the order of the Byzantine battle array with the disorder of barbarian military dispositions. Manuel is credited with greatly expanding the pronoia system. In the reign of Alexios I pronoia grants were limited to members of the imperial family and their close connections; Manuel extended the system to include men of considerably more lowly social origins and foreigners. Both classes of new pronoiar infuriated the historian Choniates, who characterised them as: tailors, bricklayers and "semi-barbarian runts". Permanent military camps were established in the Balkans and in Anatolia, they are first mentioned during the reign of Alexios I (Kypsella and Lopadion), but as Lopadion is recorded as being newly fortified in the reign of John II it is the latter who seems to have fully realised the advantages of this type of permanent camp. The main Anatolian camp was at Lopadion on the Rhyndakos River near the Sea of Marmara, the European equivalent was at Kypsella in Thrace, others were at Sofia (Serdica) and at Pelagonia, west of Thessalonica. Manuel I rebuilt Dorylaion on the Anatolian plateau to serve the same function for his Myriokephalon campaign of 1175–76. These great military camps seem to have been an innovation of the Komnenian emperors, possibly as a more highly developed form of the earlier aplekta (military stations established along major communication routes), and may have played an important role in the improvement in the effectiveness of the Byzantine forces seen in the period. The camps were used for the training of troops and for the preparation of armies for the rigours of campaign; they also functioned as supply depots, transit stations for the movement of
