Dedication to the Sherwood Foresters who served during World War 1

Plaque reads:
To the memory of 11,409 men of all ranks of the Sherwood Foresters (Nottinghamshire and Derbyshire Regiment) who gave their lives for their King and their Country in the Great War 1914 - 1919 and in honour of the 40,000 of their comrades who served during the war in Thirty Two Battalions of the Regiment. This Monument is gratefully erected by the people of the counties of Nottingham and Derby
To Remind us of their sacrifice and our duty
Authors Note:
I do not know if the significance of the reference to the 'Great War 1914 - 1919', or if this is an error on the stonemason's part.
