The boundary layer thickness is usually defined as the distance from the wall to the point where the flow velocity reaches 99 % of the free stream value.
In the very thin boundary layer associated with free stream flows with high Reynolds numbers, a steep rise in velocity occurs perpendicular to the wall.
Boundary layer thickness = 0.37*Distance on x-axis/(Reynolds Number^(1/5))
δ = 0.37*x/(Re^(1/5))
This formula uses 3 Variables:
Variables Used
Boundary layer thickness - (Measured in Meter) - Boundary layer thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity.
Distance on x-axis - (Measured in Meter) - Distance on x-axis is the distance of point measured along x-axis form origin.
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

Answer:
Resistance (i.e., war and military resistance); sometimes this included attempts to draw upon supernatural solutions to avoid or to undo conquest.
Acquiescence—often this meant trying to negotiate the best terms possible;
Alliance—sometimes it was possible to join with the Europeans in conquest of neighbours (often traditional enemies with whom they had long been in conflict anyway).

The native Americans already had the first 3 items. The British brought horses to the new world and the native Americans used them a good bit Civil War and after.
