Explanation:

The move was planned by a local political faction linked to the Panama Canal Company, a French-American company that was interested in building a waterway connecting the Atlantic and the Pacific through the isthmus of Panama. The proclamation date is November 3, 1903. The action enjoyed the tacit approval of the Theodore Roosevelt administration. It impeded an armed response from Colombia by paralizing local trains and sending a US Navy ship.
