The Swedes being still very hard pressed in Germany, the Queen sent fresh orders to her Ambassador at Paris to represent their situation to the King. Grotius demanded an audience, which he obtained on the 1st of October, 1637, at St. Germains. He assured his Majesty, that it was not without reluctance he so frequently laid the necessities of the allies before him, and the importance of their being assisted by France, but he did it by express order; that he was particularly charged with two things; first, to compliment his Majesty on the advantages gained in Piccardy and Burgundy; and secondly to solicit him to send speedily a powerful force over the Rhine. He added, that the Queen would not have thought this request necessary, had she received the letters in which he gave her a particular account of what passed at the last audience he had of his Majesty. He beseeched the King to be pleased to give orders that the promises, which he had graciously made, might be speedily executed. He represented, that if succours were not immediately sent into Germany, the Austrians, after vanquishing their enemies, would go and overpower the Duchess of Savoy the King's sister, and penetrate into France. He afterwards shewed that the Swedish army was in great danger of being overwhelmed, if a powerful diversion were not speedily made. After this speech, Grotius presented a letter from the Queen, of the 19th of August, 1637. Lewis XIII. replied to the Swedish Ambassador, that he was determined to fulfil his promises; that he had already sent some troops to the Duke of Weymar; that he would speedily send him a farther reinforcement, and employ all the forces of his kingdom in defence of his sister the Duchess of Savoy.
