On the eleventh day of September, early in the morning, the confederates, favoured by a thick fog, erected batteries on each wing and in the centre; and about eight o'clock, the weather clearing up, the attack began.

Eighty-six battalions on the right, commmanded by general Schuylemburgh, the duke of Argyle, and other generals, and supported by two-and-twenty battalions under count Lottum, attacked the left of the enemy with such vigour, that, notwithstanding their lines and barricadoes, they were in less than an hour driven from their intrenchments into the woods of Sart and Tanieres.

The prince of Orange and baron Fagel, with six-and-thirty Dutch battalions, advanced against the right of the enemy, posted in the wood of La Merte, and covered with three intrenchments.

Here the battle was maintained with the most desperate courage on both sides.

The Dutch obliged the French to quit the first intrenchment; but were repulsed from the second with great slaughter.
