Their departure preceded that of Florence Nightingale, but at Grant's request they remained in Paris so that the Nightingale party could join them. While in Paris, Moore visited hospitals there to study nursing practice and gathered surgical supplies and instruments that later proved very useful at the field hospitals in Crimea. On 4 November the groups arrived in Constantinople, and Moore took charge of the stores, kitchens and the orderlies of these departments. Nightingale's party and the other sisters took charge of the old Turkish barracks converted into a makeshift hospital with 2,500 wounded. Moore was later assigned to the barracks hospital in Scutari, Turkey in 1855, nursing victims of an outbreak of cholera alongside other Sisters of Mercy such as Mother Mary Francis Bridgeman and Sister Aloysius Doyle. On 28 April 1856 she returned to London after a serious illness. Nightingale acknowledged her indebtedness to Moore's nursing duties and paid tribute to her qualities in a letter from Balaclava. Moore and Nightingale would have a lifelong friendship. Moore is included in the painting The Mission of Mercy by Jerry Barrett which depicts Nightingale receiving a wounded soldier at the Barrack Hospital. In 1868, Moore oversaw the publication of The Practical Sayings of... Catherine McAuley'. Moore died in the Convent of Mercy, Bermondsey on 13 December 1874, and is buried in the convent cemetery. While Moore was dying, Nightingale wrote that "It is we who are left mother-less when she goes."
