For a long time Regniéville was the advance-post of the French line between Mort-Mare Wood, _on the left_, and Prêtre Wood, _on the right_. At the beginning of April, 1915, the French advance was especially dangerous for the enemy, whose counter-attacks became more frequent. It was evident that the slightest advance in the direction of Thiaucourt would hamper the German communications between Metz and St. Mihiel, and would hinder the revictualling of the troops as well as the steady supply of reinforcements and munitions. That is why, on April 9, the Germans made fifteen successive attacks to drive the French from their trenches and the edge of Mort-Mare Wood. [Illustration: AMERICAN GRAVES AT REGNIÉVILLE] _Keep on towards_ =Thiaucourt.= _To the left of D. 15 there is an_ American cemetery (_photo below_), _500 yards from Regniéville. 1 km. further on, fifty yards from the road, and before entering_ =Four Wood=, lies a derelict Renault tank (_photo above_), _and beside it_ the graves of its drivers. _In the Wood are_ numerous German gun emplacements. [Illustration: FOUR WOOD _Smashed Renault Tank at the edge of the wood_.] _On reaching the crest_ (Hill 340), _on the right, alongside Saules Wood, are_ two German gun shelters. _Further on, at the “milestone” 4 km. from Thiaucourt, is a_ concrete blockhouse (_photo below_). _From I.C. 13, D. 15 descends in a large bend across_ =Heiche Wood.= _One kilometre from Thiaucourt, in a ravine on the right of D. 15, there stood_ a large railway station and an important German military depot. _On the other side of the road there is a_ German cemetery containing 600 graves. =Thiaucourt=, altitude 750 feet, stands in an amphitheatre, in the centre of a loop described by the Rupt-de-Mad stream. A large number of its houses are in ruins, especially on the banks of the Rupt. Thiaucourt was a rest-camp behind the German lines. Numerous huts were erected on the banks of the stream, many vestiges of which still remain. _After crossing the Rupt-de-Mad in_ Thiaucourt, _keep along the street which continues the bridge and rises to the end of the town. On the right, towards the last of the houses, is I.C. 13, leading to_ =Jaulny.= [Illustration: THIAUCOURT ROAD (D. 15). MACHINE-GUN BLOCKHOUSE] _Recross the Rupt-de-Mad at the entrance to Jaulny. Take to the left, along the river, the road running through the village_, many of whose houses were damaged by shells. [Illustration: THIAUCOURT. BRIDGE OVER THE RUPT-DE-MAD] _On leaving Jaulny there is_ a large German cemetery _on the right_. _I.C. 13 runs through a pretty valley, alongside the Rupt-de-Mad and passes near the railway station._ The old road having been destroyed by the explosion of a German ammunition train, _a new road enables the tourist, by crossing the river, to reach the village of_ =Rembercourt= _on the left bank_. The bridge was blown up and many of the houses are in ruins.
