From the foregoing it is apparent that the manoeuvres of Moreau were not wisely planned. In appearance only they seemed to be less hazardous than those of Bonaparte. After magnifying the difficulties of crossing the Rhine with the four French corps at Schaffhausen, Moreau adopted a course which was much more complicated, which required a longer time to execute, which involved several strategical errors, and which, as will be shown later, did not allow Moreau to take all the advantages of the angular base of operations due to his possession of Switzerland. Though these manoeuvres were successful, it is not because they were wisely planned, but because there was little or no opposition to their execution. They were successful because Kray, not appreciating the situation, failed to profit by the mistakes of his adversary. It will now be of interest to examine into the operations of Moreau after he had united the bulk of his forces in the vicinity of Schaffhausen. On the 1st of May the four French corps were thus stationed: Moreau's and Lecourbe's at Schaffhausen, St. Cyr's at Stuhlingen, and Ste. Suzanne's at Neustadt. From these positions the French advanced to attack Kray. Lecourbe with twenty thousand men marched on Stokach to capture that place, and to drive back the Austrian reserve of twelve thousand there; Moreau moved on Engen with forty thousand men and there encountered Kray with forty-five thousand; St. Cyr directed his corps on Zollhaus; and Ste. Suzanne remained in the vicinity of Neustadt. In front of St. Cyr and Ste. Suzanne there were a few thousand Austrian troops more or less scattered. Kienmayer's corps yet remained along the western edge of the Black Forest, and Starray's corps was still farther away toward the north. Though Moreau had assembled three of his corps, numbering eighty-five thousand men, in such positions that they could easily have concentrated upon a single battle-field, and have outnumbered Kray almost two to one; yet, at the battle of Engen, he was outnumbered by his adversary. St. Cyr's corps was so far away to the left that it had scarcely any effect in deciding the battle. Evidently this corps should have been so directed that it could have re-enforced the right of Moreau or the left of Lecourbe. Had this been done, the battle of Engen would have been a great victory. Then Moreau could have hurled the Austrians back into the Black Forest, and have severed their communications with Ulm. In short, Moreau should have advanced with his right, instead of his left, strongly re-enforced. In order to reap the full advantages of the flank position which he occupied, every effort should have been made so to defeat the Austrians as to get possession of their communications. Moreau failed to appreciate this fact. His faulty movements enabled Kray, after the battle of Engen, to fall back to Mosskirch; and, by so doing, to retain possession of the road to Ulm.
