D'Argenson might beg and entreat, and write despatches: but he was powerless to enforce his words with the weight of his little finger.[321] On the 10th of March he drafted a reply to Frederick, in which he undertook that the army of Bavaria should be reinforced and should push the war with vigour. The reply never went to Berlin; it remains marked with the words "n'a pas servi."[322] Indeed the French policy was already decided. For no political reason whatever, the King had set his heart upon a campaign in Flanders; and to that desire his own interest, the interest of his allies, and every statesmanlike consideration must of necessity yield. He was not likely to meet with resistance from Noailles, still less from Count d'Argenson or Maurepas; and the Foreign Minister stood alone in fruitless opposition to this brilliant piece of political fatuity. The effects of it were apparent already. The arms of France were paralysed in Germany in order that troops might be concentrated in Flanders; the army of Bavaria could not be reinforced; little could be done for the army of the Main; and d'Argenson, while persistently demanding ready co-operation in his overtures at Dresden, was obliged to evade and trifle with the equally persistent demands of Frederick. His position was a very thankless one; and it would have been as ridiculous as it at first would seem, had it been of his own choosing. That it was not, there is ample evidence to prove. From this anomalous disposition of the French Government the four decisive events of the year 1745 descend in lineal succession. Each was a political disaster of the first magnitude; every one of them was richly deserved, and not one was really attributable to the Minister who has ordinarily borne the burden and the blame. Those events are--first, the loss of Bavaria; second, the Convention of Hanover; third, the election of Francis I.; and fourth, the Treaty of Dresden. It was on the 21st of January that the young prince Maximilian succeeded to the Electorate of Bavaria; on the 19th of April he signed a convention with Maria Theresa.[323] The Emperor on his death-bed had adjured his son to rely on the support of France;[324] and Chavigny, the French minister at Munich, was ready to assure him that he would never do so in vain.[325] The Austrian troops were already in Bavaria; repeated warnings were given both by Frederick and Chavigny of the critical position of the young Elector; and every means of persuasion was exhausted by Chavigny in order to secure the reinforcement of the Bavarian army. The French Government were deaf to his representations; the Council rejected d'Argenson's despatches;[326] d'Argenson himself was at last irritated at the reiteration of demands with which he had no power to comply.[327] Chavigny had to pacify the Elector with promises and assurances, in default of troops.
