The Queen's consent having been obtained, Calvert set out upon his journey to the frontier the next day. He would have carried a lighter heart had he felt better assured of the good faith of the King and Queen. Louis had given his consent readily enough and had approved heartily of the plan, for it had ever been against his real wishes to call in the aid of the allies, but Calvert knew too well how little he dared rely on the King's firmness or courage. As for the Queen, he could only hope that the continued representations of Beaufort, Favernay, and others about her Majesty cognizant of the enterprise and the confidence she had expressed in himself, would confirm her in her resolution to help carry the undertaking through to a successful termination.

Mr. Calvert first made his way with all possible expedition back to Maubeuge, where he reported to Lafayette the result of his interview with their Majesties and received from him letters to certain officers who were to be taken into the enterprise and whose commands were to be won over if possible.

"Her Majesty can surely no longer doubt my good faith," said Lafayette, bitterly, to Calvert. "Success, death, or flight is all that is left to me now."

With these letters Calvert proceeded on his way to Namur, Givet, and Trèves, where different detachments of Lafayette's troops were garrisoned. He was made welcome at every mess-table, and his scheme was received with such enthusiasm that it seemed almost an unnecessary precaution to cross the frontier and seek a possible asylum for the Royal Family in case the great plan failed. But the very enthusiasm of some of these young officers caused Calvert to fear for the success of the enterprise. So loud-tongued were they in their loyalty, with such imprudence did they drink toasts to their Majesties and the success of the undertaking, that Calvert, himself so calm and silent, was both disgusted and alarmed.

With the enthusiastic promise of allegiance to the plan on their own part and that of their regiments, Calvert quitted the society of these officers, and, certain of the hearty co-operation of enough troops to make the safety of the King and Queen amply assured, he proceeded, by way of the Mozelle, to Coblentz. He arrived at that city on the 26th of July, and was immediately granted an interview with the great Prince-Elector of Trèves, but recently established in his splendid new palace on the Rhine, and the commander-in-chief of the allied army, his Grace the Duke of Brunswick.

Though Calvert had journeyed with all possible speed, he was come a day too late, and he heard with inexpressible alarm and chagrin of the imprudent manifesto issued by the Duke but the day before. Surely no other great general of the world ever made so colossal, so fatal a blunder. In that arrogant and sanguinary manifesto could be heard the death-knell of the unhappy King of France, or so it seemed to Calvert, who was so deeply impressed with the rashness and danger of his Grace's diplomacy that he made no attempt to conceal the alarm he felt. This open disapproval so offended the Duke and his friend, the Prince-Elector, that the latter received Calvert's proposals with the utmost coldness, and would make no promise to receive the royal fugitives in case it became necessary. Perhaps, too, he was weary of royal guests. Seeing that nothing was to be got from the Elector, Calvert hurried on to Worms through that beautiful Rhine country which he had once traversed so leisurely and delightfully with Mr. Morris.

There he found Monsieur le Prince de Condé, with whom he had a long audience. This great leader of the emigrant forces, being apprised of Calvert's embassy, approved heartily of that scheme which would make the King openly join issue with his nobles, and sent the young man on with all speed to Kehl with secret letters for Monsieur de Vioménil. This General, under Monsieur de Condé's orders, was stationed with trusty troops from Luckner's command at the little town of Kehl, opposite Strasburg, and was deep in secret negotiations with officers of the garrison for the capitulation of that city and the entry of the emigrant army. These intrigues had been going on for some time, and so crafty were Vioménil's plans (he was the greatest diplomat the émigrés could boast), and so successful was Monsieur de Thessonnet, aide-de-camp to the Prince de Condé, in carrying them out, that when Calvert arrived at head-quarters the possession of Strasburg by the emigrant forces seemed to be a question of only a few days. 'Twas in this belief that Monsieur de Condé had despatched Calvert to Monsieur de Vioménil, who joined in the enterprise with the utmost enthusiasm and confidence. So assured was he of the success of his own undertaking that he spoke of it almost as if 'twere already an accomplished triumph, even going to the length of showing the young man the method of attack and occupation traced upon the plan of the city; at this street a regiment was to be stationed; at that gate a body of cavalry was to enter—as though he were master of fate and naught could interfere with his plans. So confident was Vioménil, and so impregnable a defence did Strasburg seem to offer for the King should misfortune overtake him, that Calvert set out on his journey back to Maubeuge the following day buoyed up with the belief that should the army refuse its allegiance and support the King would find, at any rate, a safe asylum at Strasburg. But already Brunswick's ill-advised manifesto was at work overthrowing these well-laid plans, which were to come to nothing, as were his own, unhappily, though for a different reason.

At Maubeuge, where he arrived on the 1st of August, gloomy forebodings in regard to the disastrous effects of his Grace of Brunswick's manifesto were fully shared by Lafayette and those officers committed to the conspiracy. Indeed, Lafayette was in the greatest anxiety and dismay.

"We must force our hand," he said to Calvert. "There is not a moment to lose. This cursed, imprudent, vainglorious mandate of Brunswick's has set the whole country by the ears, for all Paris and the army believes, aye, knows, that the King had cognizance of it before it was issued. The Queen has usually been the double dealer, but this time I think they have both had a hand in it, although these letters from your wife, which, according to our agreement, I have opened, assure us that their Majesties are still of a mind to trust to the issue of our plan and are ready to make the trial at any moment."

"What success have you had with the army?" asked Calvert.

"Much. I can count on a dozen regiments—Saurel, Marbois, Pelletet, and their commands will go with me. I have favorable news, too, from Namur and Tréves; but there is no more time, I think, to gain over others. We must work with what we have. The advices from Paris make it plain that the King is all but lost," and he laid before Calvert a budget of despatches lately arrived by couriers from the capital. "You will see for yourself in what a ferment the city is, and how bitterly hostile is the attitude of Assembly and people to the King."

"And what do you hear from Beaufort, Monciel, and the rest who are working with the members of the Assembly?" asked Calvert, who had heard nothing on his long journey, though he had kept their Majesties informed of his own movements.

"Here is Beaufort's letter—it reached me yesterday," replied Lafayette. "He reports a sufficient number engaged on our side by bribery or interest to insure the King's departure—only it must be instantly, instantly, or all is lost."

"Then I will go at once to Paris," said Calvert, "and report all ready here, and the great step must be taken if it is ever to be."

"It cannot be too soon."

"And have you made all arrangements?"

"This is my plan," says the General, laying a military map of France upon the table before Calvert.

"The King must ask permission to retire to Compiègne for a few days—'tis, as you know, one of his Majesty's favorite residences, hence the request will seem natural. Three days pr............
