Major General Sir Charles Snodgrass Ryan, KBE, CB, CMG, VD (20 September 1853 – 23 October 1926) was an Australian surgeon and army officer.
[2] In September 1876, Ryan entered the Turkish service, and was forthwith sent to Nisch, where he was placed in charge of a large hospital during the Serbian war.
[2] He was afterwards sent to the Orchanie Balkans in charge of 3000 Turkish soldiers, and from there was ordered to march to Widdin, although still suffering from a severe attack of dysentery.
From Widdin he proceeded with Osman Pacha to Plevna, which he gained after marching for three successive days and nights, and was present at the first battle of that memorable conflict, being the only doctor on the field.
[2] On 8 September his horse was shot under him, and his attendant killed by his side, while riding into one of the Turkish redoubts, which was about to be attacked by Russian general Michael Skobeleff.
At the outbreak of the First World War in 1914, Ryan became assistant director of medical services, 1st Division, Australian Imperial Force.
