'At around quarter to ten in the morning, before the Venetian and Zaratin fleets met in the Zara Channel, a second enemy flotilla was sighted approaching from the north by Venetian lookouts. The decision was quickly made by the leaders of the Grand Fleet that measures would need to be taken to prevent the oncoming secondary fleet from interfering in the main battle against the Zaratins. A 'wing', made up of around ten to twelve galleys was dispatched north, to engage the smaller northern force and prevent it from flanking the Venetians during the battle.
Almost at ten, the hour, a third fleet was seen rounding the headland at the small village of Poljana, coming from the south. This time, a fierce debate took hold between the leaders of the expedition on the Venetian flagship. The Grand Fleet was within minutes of engaging the Zaratins meeting them head on from the south-east. But the wind was from the south, and the likelihood of the third fleet arriving in time to intervene in the battle was high. The choice was therefore between attempting to defeat the main Zaratin force quickly and then turning against the newcomers, or to divide the flotilla.
They chose to divide. Around fifteen galleys turned against the wind and rowed to intercept the southern enemies. Somewhere around twenty Venetian galleys remained to face the primary, somewhat smaller Zaratin fleet.
From the spires of Zara, those observing the battle as it unfolded (including the Comes of Zara, Antonio Begna) were grimly satisfied. The operation to disperse the Venetian fleet was succeeding. However, the Venetians still outnumbered the Dalmatian forces (the primary and southern fleets were Zaratin, but the northern fleet was composed of a combination of Crepsan, Arban and Veglian ships under the command of Croat-Zaratin noble Domaldus) and was composed largely of veterans of the 1202 campaigns.
At 10:15 on the 6th of February 1203, the main Venetian and Zaratin fleets met in the centre of the Zara Channel. The Zaratin ships were smaller, but faster. Laden with bowmen and equipped with specialist hook-poles for tearing sails, they were able to strike the Venetians at a distance. But the Venetian galleys were manned with formidable rams which could tear the hulls of the smaller Zaratin ships to matchwood.
At the moment the two came together, the Zaratins divided. Blessed with favourable winds, half of the swift ships turned suddenly northwards and sailed at full speed towards the northern 'wing' dispatched by the Venetians. At the same time, the remaining half (which split off just a few moments before the brief meeting of the two fleets) rowed southwards towards the southern wing as fast as the wind would allow.
The Venetians were paralysed by the shock of the sudden change in tactics. The larger Venetian galleys could not hope to match the speed of the ships hurrying north. Nor could they hope to catch the Zaratins rowing south, for their enemy had already lowered their sails in preparation for the change in direction, while the Venetians would be delayed by the process of doing the same. Meanwhile, the northern and southern wings of the Grand Fleet were imperilled, caught in the vice of the Dalmatians.
To make matters worse, yet another fleet was sighted by the Venetians. From the west, emerging from the natural harbour at Sutomišćica, an assembled squadron of ships from the southern cities (including Ragusa and Spalatro) moved inexorably towards the Grand Fleet. It was small - perhaps bringing the balance between the Dalmatians and Venice to roughly equal - but dangerous due to the perilous situation in which the Venetians found themselves.
Unbeknown to Venice, their chances were about to become even more hopeless. From the south, as yet unseen by either side, a force of Genoese, Pisan, Gaetan and Anconine* reinforcements were rapidly approaching, hastened by the southern winds. They had congregated at Corfu (over which the Genoese had cemented their control, enlisting their privateers already installed there to assist in the cause) and made for Zara together. Their imminent arrival** was unknown even to the Zaratin Comes.
In the moment, the Venetians made the decision to further divide their forces. They could only hope that their split main force could reach the northern and southern wings in time to assist in the battle.'

*For those wondering, the Anconines met with the Genoese, Pisans and Gaetans at Kornati - no need for Ancona to dispatch ships to Corfu when Dalmatia lies just across the Adriatic. Expect more on Ancona later!
** I know that I wrote the Italian states had already sent aid - and they have. Their crews and ships are under direct command of Zara. The reinforcements referenced in this post are new and under their own command.
