I thought you might like to see this. Drawn by Lieutenant (and later Captain) H. M. Boyd, Royal Engineers, and kindly lent to me for use on this site by a member of his family (who naturally holds the copyright), it shows the area referred to as “Spoilbank” early in 1917.
Take a look at this trench map (click to enlarge) which shows the route of the first part of our Zillebeke tour. Down near the bottom left hand corner you can see that “Spoilbank” is marked, just south of the Ypres-Comines Canal, with the green dot signifying Spoilbank Cemetery, directly opposite on the northern side of the canal. You can even see “Blighty Bridge”, as Captain Boyd refers to it in the sketch, crossing the canal if you look carefully. “Not to be used in daylight”. Indeed not.
