President Monroe likewise found the matter very grave, and he therefore consulted Thomas Jefferson.

At that time Jefferson had retired from public life and was living quietly at his place in Virginia.

That President Monroe's communication deeply stirred him is to be seen in his reply, written October 24, 1823.
Jefferson says in part: "The question presented by the letters you have sent me is the most momentous which has ever been offered to my contemplation since that of independence....

One nation most of all could disturb us....

She now offers to lead, aid and accompany us....
With her on our side we need not fear the whole world.
