This is known
as the Red Lined Map.The line which gives it its
name can be seen clearly. What does it signify?
War of Independence ended in 1783 with a humiliating defeat for
Britain. The red line was used by the British negotiating for peace
with the Americans to demonstrate their interpretation of the boundary
between the United States and the provinces which later formed Canada.
The map was presented to George III to show him how the proposed
boundaries might work.
