Documentary History of the State of New York, Vol. III
Fortliwitli some began to cut down timber ; others to pull oif bark to cover lodges to shelter them ; otliers to fall large trees with which to barricade their lodges on the sliore. They know so well how to construct these barricades, that five hundred of their enemies would find considerable difficulty in forcing them in less than two houi-s, without great loss. They do not fortify the side of the river along which their canoes are ranged, so as to be able to embark should occasion require.
After they had camped, they despatched three canoes with nine good men, as is their custom at all their encampments, to reconnoitre witliin two or tlu-ee leagues, if they see anything. After which they retire. They depend the wliole night on the exploration of the van guard, which is a bad habit of theirs. For sometimes their enemies surprize them asleep, and kill them witliout having an opportunity of recovering their feet to defend themselves.
Remarking that, I remonstrated with them against the error they committed ; told them to watch, as they saAV us do, all night, and to have out-posts to spy and see if they could perceive anything ; and not to live in that style, like cattle. They told me they couldn't watch, and that they laboured all day hunting. So that, when they go to war they divide their force into tliree -- to wit -- one party, scattered in divers places, hunting ; another forms the main body, wliich is always under arms ; and another party as a van guard, to scout along the river and see whether they will not discover some trail or mark indicating the passage of friends or enemies. This they ascertain by certain marks the chiefs of one nation give to those of another, which are not always alike -, notifying each other from time to time wlien they alter any.
