The Grave Registration Unit's battlefield cross for Capt. C Collingwood - now in All Saints' Church, Newton-le-Willows. If you look closely, you can see where there is rot at the level it protruded from the ground. You can also see in the photograph below the original cross erected by his unit - but presumably destroyed as the war moved to and fro.
The cocarde, or roundel, on the cross would have been put there post-June 1918, when the order was given to mark all 55th Division graves in this manner.
A rare survival.
The motto comes from this poem, written by Lt. LG Wall, kia, 9 June 1917.

When Princes fought for England's Crown
The house that won the most renown
And trod the sullen Yorkist down
Was Lancaster

Her blood red emblem, stricken sore
Yet steeped her pallid foe in gore,
Still stands for England ever more
And Lancaster

Now England's blood like water flows,
Full many a lusty German knows
We win or die who wear the Rose
Of Lancaster
