"The delay entailed in collecting the Allied forces, together with the uncertainty of the threat towards Mons had given Marshal de Saxe time to prepare a favourable position on which to receive the Pragmatic Army, and given the fact that he already had all his engineers from the siege of Tournai on site to oversee the construction of his battlefield fortifications, it is small wonder that he himself thought his position almost impregnable.
The French right wing was anchored firmly on the river Scheldt at the fortified village of Antoing.Here the houses had been turned into miniature fortresses, the streets were barricaded and slit trenches were dug around the outskirts of the village to enable an even greater volume of fire to be delivered by the defenders. On the east bank of the Scheldt a strong battery of artillery was installed so as to enfilade any advance on Antoing from the south. From Antoing the French line extended to the west for just over a mile until it reached another fortified village, Fontenoy. Along this line de Saxe had constructed three redoubts each about 400 meters apart. These were not just constructed as a kind of breakwater upon which the enemy columns would have to loose formation in order to attack and then reform after passing between them, but also to facilitate counterattacks, allowing the French cavalry to flow through in pursuit of a beaten foe.
The village of Fontenoy, like Antoing was turned into a strongpoint with cannon placed to cover every approach. From here the French line turned at right angles to the north for approximately 1000 meters following the course of a sunken road across a plateau leading to the Bois de Bary (Wood of Barry). Behind the sunken road de Saxe placed two lines of infantry, supported by two lines of cavalry of around 60 squadrons.
On the French left, in and around the Bois de Bary, de Saxe lavished still more of his considerable talents in field fortification. The wood was lined with infantry and many of the trees had been felled to form abattis. Two strong redoubts were constructed at the eastern side of the wood to dispute any turning movement, the most famous of these being known as the Redoubt D’Eu which had been built at the south-eastern tip of the Bois de Bary so as to enfilade any advance made by the Allies against the French centre. In support of this position was a reserve of picked infantry and cavalry regiments, including the Irish Brigade, the “Wild Geese”. In all the French army numbered 93 battalions,146 squadrons and 80 cannon, some 70,000 troops, of which 27 battalions and 17 squadrons were left to cover Tournai."
