Real military characters had already formed their opinion of this officer, and saw a presumptuous charlatan where others had admired an able warrior. His own conduct soon convinced them that they neither had been rash nor mistaken. The King of Naples demanding, in 1798, from his son-in-law, the Emperor of Germany, a general to organize and head his troops, Baron von Mack was presented to him. After war had been declared against France he obtained some success in partial engagements, but was defeated in a general battle by an enemy inferior in number. In the Kingdom of Naples, as well as in the Empire of Germany, the fury of negotiation seized him when he should have fought, and when he should have remembered that no compacts can ever be entered into with political and military earthquakes, more than with physical ones. This imprudence, particularly as he was a foreigner, excited suspicion among his troops, whom, instead of leading to battle, he deserted, under the pretence that his life was in danger, and surrendered himself and his staff to our commander, Championnet.
A general who is too fond of his life ought never to enter a camp, much less to command armies; and a military chief who does not consider the happiness and honour of the State as his first passion and his first duty, and prefers existence to glory, deserves to be shot as a traitor, or drummed out of the army as a dastardly coward. Without mentioning the numerous military faults committed by General von Mack during this campaign, it is impossible to deny that, with respect to his own troops, he conducted himself in the most pusillanimous manner. It has often been repeated that martial valour does not always combine with it that courage and that necessary presence of mind which knows how to direct or repress multitudes, how to command obedience and obtain popularity; but when a man is entrusted with the safety of an Empire, and assumes such a brilliant situation, he must be weak-minded and despicable indeed, if he does not show himself worthy of it by endeavouring to succeed, or perish in the attempt. The French emigrant, General Dumas, evinced what might have been done, even with the dispirited Neapolitan troops, whom he neither deserted, nor with whom he offered to capitulate.
Baron von Mack is in a very infirm state of health, and is often under the necessity of being carried on a litter; and his bodily complaints have certainly not increased the vigour of his mind. His love of life seems to augment in proportion as its real value diminishes. As to the report here of his having betrayed his trust in exchanging honour for gold, I believe it totally unfounded. Our intriguers may have deluded his understanding, but our traitors would never have been able to seduce or shake his fidelity. His head is weak, but his heart is honest. Unfortunately, it is too true that, in turbulent times, irresolution and weakness in a commander or a Minister operate the same, and are as dangerous as, treason.
