Push on, my Lord of Wurtenburg, push on, across the fen!
See where the Town of Ypres calls you!
There's just one ragged British line of Plumer's weary men,
It's time they held you off before, but venture it again!
Come, try your luck, whatever fate befalls you!...
The poem first appeared in The Queen's Gift Book, published for Christmas 1915 'In aid of Queen Mary's Convalescent Auxiliary Hospitals For Soldiers And Sailors Who Have Lost Their Limbs In The War'. It was subsequently included in Doyle's The Guards Came Through and Other Poems, 1919.
Conan Doyle was devastated by the death of his eldest son in 1918. Although badly wounded on the first day of the Somme, Kingsley, as he was known, was struck down by the Spanish influenza epidemic.
