The Administration then let it be known that the United States would not recognize the new Mexican regime.

Whether Mr.Wilson would at this time have taken such a position, irrespective of the British attitude, is not known, but at this stage of the proceedings Great Britain and the United States were standing side by side.
About three weeks afterward Mr.Laughlin heard that the British Foreign Office was about to recognize Huerta.

Naturally the report astonished him; he at once called again on the Foreign Office, taking with him the despatch that he had recently sent to Washington.

Why had the British Government recognized Huerta when it had given definite assurances to Washington that it had no intention of doing so?
The outcome of the affair was that Sir Cecil Spring Rice, British Ambassador in Washington, was instructed to inform the State Department that Great Britain had changed its mind.

France, Germany, Spain, and most other governments followed the British example in recognizing the new President of Mexico.
It is thus apparent that the initial mistake in the Huerta affair was made by Great Britain.
