Legend Description

Military Engagement
These point symbols represent different types of military engagements. On the map they are coloured according to the year in which the engagement took place (black for 1812, orange for 1813, and purple for 1814). This map focuses on military engagements which took place along the border, and is not meant as an exhaustive representation of all engagements that took place during the War of 1812 (see Legend Notes below for details).

Troop Movement
These line symbols represent the major movements of British and American troops during the War.

Settled area shown represents the "ecumene" or area of generalized continuous settlement as it existed between 1812 and 1814. Unsettled areas are show as British, or American.

Layers

These layers each contain the locations and types of military engagements, as well as the troop movements which took place in 1812, 1813 and 1814 respectively. The symbols for each year are coloured differently (black for 1812, orange for 1813, and purple for 1814). The troop movements can be turned off by clicking in the check box beside this layer name. The labels for the individual military engagements can be turned on and off by clicking on the button.
Turning on a given year folder will turn off all others, and therefore, only one year can be viewed at a time.

Legend Notes

In three seasons of offensive warfare the Americans made little inroad into BNA. Instead, they lost territory in Maine, in the Mississippi valley, and Fort Astoria in the Oregon Territory. The fragmented and scattered segments of maps on this plate reflect the uncoordinated tactical actions of the American troops.
Most of the tactical actions are shown on the yearly map segments. Since it is impossible to locate every action on maps at these scales, only the principal border actions are shown. There were, of course, many actions elsewhere, such as numerous American Indian engagements in the American territories as well as British raids in Chesapeake Bay and in the New Orleans area.
See Text from the Printed Atlas for a description of the strategic thrusts, year by year.
