Smola's action at Neerwinden in 1793 was the employment of a reinforced cavalry battery supporting Austrian infantry on defense. It was not an offensive action. Smola was the supporting unit to an infantry unit on the defensive attempting to stop a French attack. It was not similar, for example, to Senarmont's action at Friedland in 1807 or Drouot's action at Lutzen in 1813. In the latter two cases, the artillery advanced against an enemy on defense being supported by infantry. The artillery in these instances were the attacking units.
Smola's action is, however, very similar to British artilleryman Willian Phillips action at Minden during the Seven Years' War. That action is described very well in the recent book Where a Man Can Go by Robert Davis.
