The Rulers of the Lakes A Story of George and Champlain

Excerpt

Young Robert Lennox and his friend Tayoga, an Onondaga Indian, undertake
to make a dangerous journey through the northern wilderness to warn the
garrison and settlers gathered at Fort Refuge of the hostile forces. 
Afterwards they join the army as scouts, preceding it on an expedition
to Lake George and Lake Champlain, where they engage in many fierce
encounters.  The story concludes with the battle of Lake George, in which
the Colonists win their first great success of the war.
