 Throughout the late spring and summer, the Samarrans and Baghdadis regularly engaged each other around the defensive fortifications of the city and inflicted many casualties on each other, but neither side was able to gain a clear advantage.Over the following months, the fighting spread to the districts neighboring Baghdad, as both sides fought to control the routes leading into the city.The Samarrans were able to limit the level of supplies reaching the defenders, but were unable to prevent the Baghdadi armies from moving in and out of the city.
