First: The movement of the French right on Stokach and Engen threatened the communications of Kray, without in the least exposing the communications of Moreau to an Austrian attack. In accordance with a maxim of war, proved by experience, Kray would therefore have abandoned any intended attack upon Ste. Suzanne, in order to fight for the preservation of his own communications. "The commander," says Hamley, "who finds himself on his enemy's rear, while his own is still beyond the adversary's reach, may cast aside all anxiety for his own communications, and call up every detachment to the decisive point, certain that the enemy will abandon his own designs, in order, if possible, to retrieve his position." Had Moreau appreciated this fact, he could have safely united three of his corps near Stokach, and have overwhelmed the Austrians with superior numbers. Second: Though Ste. Suzanne seemed to be in a dangerous position, he was not so in reality. In fact, had Kray attacked Ste. Suzanne in force near Neustadt, he would have given the French at Engen and Stokach an immense advantage; for the farther he proceeded into the Black Forest towards France, the more easily could the French sever his communications and destroy or capture his army. Third: Instead, therefore, of Moreau's being fearful lest the Austrians should concentrate against Ste. Suzanne, he should rather have hoped to see them carry out this movement. But, in either case, he should have strongly re-enforced his right by every means in his power. After the battle of Engen, Moreau continued to commit errors. At Mosskirch he attacked the Austrians with but fifty thousand men. At the beginning of the battle Kray had but forty thousand men, yet before it ended he was strongly re-enforced. During the battle St. Cyr's corps was near Geisingen and Ste. Suzanne's at Donaueschingen. Thus, for the second time, Moreau fought the Austrians with two of his corps absent. Moreover, they were far away on his left flank, when they should have been near him, or on his right flank, where they would have been able to overwhelm Kray, and sever his communications with Ulm. Had Moreau re-enforced strongly his right, and attacked Kray at Mosskirch with his four corps, or even with three of them, who can doubt what the result would have been? Undoubtedly he would have destroyed the Austrians between his army and the Danube, and could then have rapidly crossed the river and have intercepted the corps of Kienmayer and Starray. In truth, Moreau's faults allowed Kray to escape, when he should have been destroyed. They allowed him to seek safety in Ulm, where for several weeks he was able to make a successful stand.
