Being unable to induce his Assiniboine guides and interpreters to remain for the winter among the Mandans, Verendrye returned somewhat unwillingly to the Assiniboine River. He arrived on February 10th at his Fort de la Reine, as he says himself, "greatly fatigued and very ill." Verendrye in his journal gives us an excellent opportunity of seeing the thorough devotion of the man to his duty. From Fort Michilimackinac to the Missouri, by the route followed by him, is not less than 1,200 miles, and this he accomplished, as we have seen with the necessary delay of building a fort, between July 20th and December 3rd--136 days--of this wonderful year of 1738. Struggling with difficulties, satisfying creditors, hoping for assistance from France, but ever patriotic and single-minded, Verendrye became the leading spirit in Western exploration. In the year after his great expedition to the prairies, he was summoned to Montreal to resist a lawsuit brought against him. The prevailing sin of French Canada was jealousy. Though Verendrye had struggled so bravely to explore the country, there were those who whispered in the ear of the Minister of the French Court that he was selfish and unworthy. In his heart-broken reply to the charges, he says, "If more than 40,000 livres of debt which I have on my shoulders are an advantage, then I can flatter myself that I am very rich." In 1741 a fruitless attempt was made to reach the Mandans, but in the following year Verendrye's eldest surviving son and his brother, known as the Chevalier, having with them only two Canadians, left Forte de la Reine, and made in this and the succeeding year one of the most famous of the Verendrye discoveries. This lies beyond the field of our inquiry, being the journey to the Missouri, and up to an eastern spur of the Rocky Mountains. Parkman, in his "A Half Century of Conflict," has given a detailed account of this remarkable journey.
