In early November 1878, Victoria contracted diphtheria. Elisabeth was swiftly moved out of their room and was the only member of the family to escape the disease. For days, Victoria's mother, Princess Alice, nursed the sick, but she was unable to save her youngest daughter, Victoria's sister Marie, who died in mid-November. Just as the rest of the family seemed to have recovered, Princess Alice fell ill. She died on 14 December, the anniversary of the death of her father, Prince Albert. As the eldest child, Victoria partly assumed the role of mother to the younger children and of companion to her father. She later wrote, "My mother's death was an irreparable loss ... My childhood ended with her death, for I became the eldest and most responsible."
