She provided nursing care in the Crimean war, and was a most important part of the Army medical staff team. She revolutionized nursing. She was later to influence the Army and the Crown to start a Medical Staff Corps to administer health care expressly so as to improve it. She was loved by the soldiers she nursed.

Life-giving God, who alone hast power over life and death, over health and sickness: Give power, wisdom, and gentleness to those who follow the example of thy servant Florence Nightingale, that they, bearing with them thy Presence, may not only heal but bless, and shine as lanterns of hope in the darkest hours of pain and fear; through Jesus Christ, the healer of body and soul, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever.
