I related how Dave fell in with Washington and became his assistant, and
how, later on, Dave became a soldier to march under Washington during the
disastrous Braddock campaign against Fort Duquesne.

General Braddock's failure to bring the French to submission cost James
Morris dearly. His trading-post was attacked and he barely escaped with his
life. Dave likewise became a prisoner of the enemy, and it was only through
the efforts of a friendly Indian named White Buffalo, and an old frontier
acquaintance named Sam Barringford, that the pair escaped to a place of
safety.

War between France and England had then become a certainty. France was
aided greatly by the Indians, and it was felt by the colonists that a
strong blow must be struck and without delay. Expeditions against the
French were organized, and in the second volume of the series, called
"Marching on Niagara," are given the particulars of another campaign
against Fort Duquesne (located where the city of Pittsburg, Penn., now
stands) and then of the long and hard campaign against Fort Niagara. Dave
and Henry were both in the contest, for they had joined the ranks of the
Royal Americans, as the Colonial troops were called.

With the fall of Fort Niagara the English came once again into possession
of all the territory lying between the Great Lakes and the lower
Mississippi. But Canada was not yet taken, and there followed more
campaigns, which have been described in the third volume of the series,
called "At the Fall of Montreal." In these campaigns both Dave and Henry
fought well, and with them was Sam Barringford, who had promised the
parents that he would keep an eye on the youths. Henry had been taken
prisoner and Barringford had been shot, but in the end all had been
re-united, and as soon as the old frontiersman was well enough to do so,
