The outline of events in Canada which we have previously traced carried us to a point where the first collision in the Valley of the Ohio between the troops of the two great nations who were contending for the mastery of the northern portion of the continent had already taken place. News of this contest reached New Orleans, and reports of what was occurring at the North served to fill out the Louisiana despatches. From this source we learn that the Chevalier de Villiers,[78] a captain stationed at Fort Chartres, solicited the privilege of leading an expedition to avenge the death of his brother Jumonville, who had been killed by the Virginian force under Washington. The request was granted; and thus the troops from the East and from the West participated in these preliminary contests in the Valley of the Ohio.[79] It is not within the proposed limits of this sketch to follow in detail the military events with which each of the few remaining years of French domination in America were marked. The death-struggle was protracted much longer than could have been anticipated. The white population of the English colonies is said to have been over ten times greater than that of Canada in 1755; and yet these odds did not fairly express the difference between the contending Powers.[80] The disproportion of the aid which might be expected from the mother countries was far greater. The situation was the reverse of what it had been in the past. England began to show some interest in her colonies. She was prosperous, and the ocean was open to her cruisers. The French experiments at colonization in America had proved a source of expense so great as to check the sympathy and crush the hopes of the Court. The vessels of France could only communicate with her colonies by eluding the search of the English ships widely scattered over the sea. Although no formal declaration of war was made until 1756, England did not hesitate to seize French merchant-vessels and to attack French men-of-war, and she backed the pretensions of her colonists with solid arguments clad in red coats and bearing glittering bayonets. France shipped a few soldiers and some stores to Canada. Some of her vessels succeeded in running the gauntlet of the English cruisers, but more were driven ashore or captured. The native Canadians, more French than Frenchmen themselves, rallied to the support of the Government which had strangled every sign of independent life in their country. Old men and children joined the ranks to repel the invader; and again we have the story repeated of scant crops improperly harvested because of lack of field hands, and thereafter actual suffering for food in this old and well-established colony. The experiences of Braddock and of Dieskau were needed to teach Europeans the value of the opinions of provincial officers in matters of border warfare. Temporary successes during several years inspired hopes in the minds of the French and thwarted the progress of the English.
