Bishops arrived in Ephesus over a period of several weeks. While waiting for the other bishops to arrive, they engaged in informal discussions characterized as tending to "exasperate rather than heal their differences". The metropolitan of Ephesus, Memnon, was already present with his 52 bishops. Nestorius and his 16 bishops were the first to arrive shortly after Easter. As archbishop of the imperial city of Constantinople, he traveled with a detachment of troops who were under the command of Count Candidian. McGuckin notes that the troops were not there to serve as Nestorius' bodyguard but to support Candidian in his role as the emperor's representative. However, McGuckin theorizes that Candidian's progressive abandonment of neutrality in favor of Nestorius may have created the perception that Candidian's troops were, in fact, there to support Nestorius. Candidian ordered all monks and lay strangers to leave the city; he further instructed the bishops not to leave on any pretext until the council was concluded. Several sources comment that the purpose of this injunction was to prevent bishops from leaving the council to appeal to the emperor directly.
