Following the death of Emperor Nicholas I on , the Legion received the name "Greek Legion of Emperor Nicholas I" (). The Greeks suffered in Sevastopol, especially from the typhus that broke out in February: of the 743 men on the lists in late March, almost 200 were hospitalized. According to Chrysovergis, 96 died of typhus. The hardships and disease, as well as the realization that the hoped-for liberation of the Balkans from Ottoman rule was receding into the distant future, also demoralized many volunteers; about a hundred resigned.
