THE GREEKS ARE RECONCILED TO THE CRUSADERS - JOHANNIZZA DESIEGES DEMOTICA
When the Greeks who were in the host with Johannizza - the same who had yielded themselves up to him, and rebelled against the Franks - when they saw how he destroyed their castles and cities, and kept no covenant with them, they held themselves to be but dead men, and betrayed. They spoke one to another, and said that as Johannizza had dealt with other cities, so would he deal with Adrianople and Demotica, when he returned thither, and that if these two cities were destroyed, then was Roumania for ever lost.
So they took messengers privily, and sent them to Vernas in Constantinople. And they besought Vernas to cry for pity to Henry, the brother of the Emperor Baldwin, and to the Venetians, so that they might make peace with them; and they themselves, in turn, would restore Adrianople and Demotica to the Franks; and the Greeks would all turn to Henry; and the Greeks and Franks dwell together in good accord.
So a council was held, and many words were spoken this way and that, but in the end it was settled that Adrianople and Demotica, with all their appurtenances, should be bestowed on Vernas and the empress his wife, who was sister to the King Philip of France, and that they should do service therefor to the emperor and to the empire. Such was the convention made and concluded, and so was peace established between the Greeks and the Franks.
Johanizza, the King of Wallachia and Bulgaria, who had sojourned long in Roumania, and wasted the country during the whole of Lent, and for a good while after Easter (2nd April 1206), now retired towards Adrianople and Demotica, and had it in mind to deal with those cities as he had dealt with the other cities of the land. And when the Greeks who were with him saw that he turned towards Adrianople, they began to steal away, both by day and by night, some twenty, thirty, forty, a hundred, at a time.
When he came to Adrianople, he required of those that were within that they should let him enter, as he had entered elsewhere. But they said they would not, and spoke thus: "Sire, when we surrendered to thee, and rebelled against the Franks, thou didst swear to protect us in all good faith, and to keep us in safety. Thou hast not done so, but hast utterly ruined Roumania; and we know full well that thou wilt do unto us as thou hast done unto others." And when Johannizza heard this, he laid siege to Demotica, and erected round it sixteen large petraries, and began to construct engines of every kind for the siege, and to waste all the country round.
Then did those in Adrianople and Demotica take messengers, and send them to Constantinople, to Henry, the Regent of the empire, and to Vemas, and prayed them, for God's sake, to rescue Demotica, which was being besieged. And when those at Constantinople heard these tidings, they decided to succour Demotica. But some there were who did not dare to advise that our people should issue from Constantinople, and so place in jeopardy the few Christian folk that remained. Nevertheless, in the end, as you have heard, it was decided to issue forth, and move on Selymbria.
The cardinal, who was there as legate on the part of the Pope of Rome, preached thereon to the people, and promised a full indulgence to all such as should go forth, and lose their lives on the way. So Henry issued from Constantinople with as many men as he could collect, and marched to the city of Selyrnbria; and he encamped before the city for full eight days. And from day to day came messengers from Adrianople praying him to have mercy upon them, and come to their relief, for if he did not come to their relief, they were but lost.
