Officially, the Revolutionary Armies were operating along the guidelines set down in the 1791 Reglement, a set of regulations created during the years before the Revolution. The 1791 Reglement laid down several complex tactical maneuvers, maneuvers which demanded well trained soldiers, officers and NCOs to perform correctly. The Revolutionary Army was lacking in all three of these areas, and as a result the early efforts to conform to the 1791 Reglement were met with disaster. The untrained troops could not perform the complex maneuvers required, unit cohesion was lost and defeat was ensured.
Realizing that the army was not capable of conforming with the 1791 Reglement, commanders began experimenting with formations which required less training to perform. Many eminent French military thinkers had been clamoring for change decades before. In the period following the humiliating performance of the French Army during the Seven Years' War, they began to experiment with new ideas. Guibert wrote his epic Essai général de Tactique, Bourcet focused on staff procedures and mountain warfare, and Mesnil-Durand spent his time advocating l'ordre profond, tactics of maneuvering and fighting in heavy columnar formations, placing emphasis on the shock of cold steel over firepower.
In the 1770s, some commanders, among them the brilliant duc de Broglie performed exercises testing these tactics. It was finally decided to launch a series of experiments to try out the new tactics, and comparing them to the standard Fredrickian linear formation known as l'ordre mince which was universally popular throughout Europe. De Broglie decided that l'ordre profond worked best when it was supported by artillery and large numbers of skirmishers. Despite these exercises, l'ordre mince had strong and powerful supporters in the Royal Armée Française, and it was this formation which went into the 1791 Reglement as the standard.
