A disused quarry surrounded by a row of poplars (upper centre) marks the extremity of what was the Liepzig Redoubt. 

Thiepval Wood (known today as Bois d’Authuille) on the upper left and the 36th (Ulster) Division Memorial to its right in a wooded area. 

The Liepzig Redoubt occupied the area to the south of Thiepval, roughly from the site of the Memorial to the Missing (upper left) to the isolated clump of trees (upper right of centre). 

Thiepval on the right of the picture, the Memorial to the Missing right of centre and the area of the Liepzig Redoubt in the upper centre. 

Thiepval ridge dominated much of the surrounding area and was generally considered to be the strongest German position in the Somme sector. 

By July 1, 1916 the Germans had occupied Thiepval for exactly two years.
