SEVENTH SIEGE, A.D. 1794.
At the commencement of the campaign of 1794, General Pichegru made every possible effort to approach Tournai and besiege it in regular form, but all in vain; he, on every occasion, had to contend with troops superior to his own, beneath its walls. When, however, he had gained several victories, and the Imperialists had been conquered at Fleurus, the allies withdrew from Tournai, which fell into the hands of the French. It was not by causing men to be massacred before places that the French made their conquests, but by beating the enemy in the open field. This campaign suffices to convince military men of the vices of the ancient tactics, which began by laying sieges and sacrificed so many men in the trenches. A well-fortified place is impregnable whilst defended by a good army; but there is no fortress that can hold out, when the troops which ought to defend it are beaten. In the revolutionary wars, the French only besieged the cities that were absolutely necessary to assure the position of their armies. The king of Prussia alone formed a just idea of this new manner of making war. In 1794, he wrote to the emperor of Austria: “It is impossible to save your territories from invasion; the French have fresh armies continually springing up; and, do not deceive yourself, their generals have a good kind of tactics, which disconcerts ours and always puts it at fault.” The above passage is certainly from a French author, but it contains much truth.
