How did Great Britain interfere in the western area of the United States in the nation's early years?

It wasn't even intrusion because the locations weren't then America's part. A further explanation is provided below.

Explanation:

Throughout America, whenever the British have already invaded and conquered as well as built settlements, those who had agreed mostly with Indians that they'll go no beyond that and abandon their own country.The American community treated the country as becoming their conservative movement such that they decided to forget, slaughter Indians but instead take them away.

Ithink it's b . narratives cannot be changed by other historians later
