Title:
Napoleon

Context:
Bonaparte could win battles by concealment of troop deployments and concentration of his forces on the 'hinge' of an enemy's weakened front. If he could not use his favourite envelopment strategy, he would take up the central position and attack two co-operating forces at their hinge, swing round to fight one until it fled, then turn to face the other. In this Italian campaign, Bonaparte's army captured 150,000 prisoners, 540 cannons, and 170 standards. The French army fought 67 actions and won 18 pitched battles through superior artillery technology and Bonaparte's tactics.

Question:
In what area did the French army display superior technology to its opponents?

artillery
