Address from the C-in-C Field Marshal Sir John French to the Officers and Men of the 149th Northumberian Brigade May 1915

"The Northumberland Infantry Brigade particularly distinguished themselves under the leadership of Brigadier-General Riddell, whose loss we deplore so much. He fell at the head of his Brigade while leading you to attack the village of St. Julien. I deeply deplore the loss of one of the most gallant officers that ever lived and one of the best leaders."
