40 2 A chronological survey
Euphrates at Barbalissos to extract money from several other cities.

The
Sasanians also besieged the city of D
¯
ar
¯
a in breach of the truce, but without
success.
119
In the light of these activities Justinian did not feel bound to the
agreements any more.
120
A peace was never concluded.
The following year saw further military conflicts. This time the theatre
of war was the region of Lazika, which had been the object of dispute
earlier during the reign of Kav
¯
adh I.
121
When the Lazi made an appeal
to Xusr
¯
o I to intervene against the quartering and rule of Roman troops
within their territory the king promised to protect them from the Romans
whom Justinian had sent to fight Xusr
¯
o.
122
With a strong force the Persians
conquered Petra, a fortress situated on the Eastern coast of the Black Sea.
123
In the meantime the Roman general Belisarius, who had been recalled from
Italy and whom Justinian had sent against Xusr
¯
o in the spring of 541, arrived
in Mesopotamia. During the following years the battles in Armenia
124
and
Mesopotamia were fought with changing luck and neither of the two parties
scored a lasting success. Xusr
¯
o was hoping, however, that an advance into
Mesopotamia in the year 544 would bring a breakthrough. In particular, he
decided to conquer Edessa in order to get hold of the Roman possessions
beyond the Euphrates.
125
However, the siege of the city, which Procopius
describes at length, was not as successful as the king had hoped and the
Sasanians withdrew in return for a ransom payment.
126
Both sides were now at the point where they recognised that the annual
wars, which were more or less nothing but raids, neither achieved territorial
gains nor served either side in the long term. They entered negotiations
for a peace. While Justinian had an overall peace within the entire East in
mind, Xusr
¯
o I was only prepared for an armistice. He did not want to give
up the dominant position he enjoyed in Lazika at the time. In the spring
of 545 Justinian I gave in and had to agree to considerable payments.
127
The armistice was concluded for five years but only four years later the
confrontations resumed.
128
Until 556 the Sasanians suffered several major
defeats and were pushed back to the borders of Ib
¯
eria and the Persian part
of Armenia. Almost all of Lazika was once more under Roman control.
