The grave of the Captain Horace William Cust - Coldstream Guards. There’s an inscription on the gravestone: "In memory of Captain Horace William Cust, Coldstream Guards. He joined the Regiment on the 7th April 1848, and embarked with the 1st battalion for the Eastern Campaign, February, 1854. He served as Aide-de-Camp to Major-General Bentnick, Commanding the Brigade of Guards at the Battle of Alma, 20th September 1854, where he was mortally wounded by a cannon shot. His Grave is on the bank of the Alma. Placed by his brother, Lieut-Col. J. Francis Cust"
And on the russian: “Чтите эту могилу. В покой мертвеца упокой память его и не презри погребение его”. Russian inscription is not correct, the man who made it, don’t spoke on russian, and there’s a mistake
