Define the role of the British in the conduct of American diplomacy in the 1830s and 1840s. Cite some specific incidents where concern over British intentions or actions provoked American action.

What will be an ideal response?

ANSWER

In both Texas and California, reports of British interest propelled the U.S. government to act to protect its western flank. Both were annexed.
