He advised all Americans to leave the country, and declared that he would lay an embargo on the shipment of munitions--an embargo that would affect both the Huerta forces and the revolutionary groups that were fighting them.
Meanwhile Great Britain had taken another step that made as unpleasant an impression on Washington as had the recognition of Huerta.

Sir Lionel Edward Gresley Carden had for several years been occupying British diplomatic posts in Central America, in all of which he had had disagreeable social and diplomatic relations with Americans.

Sir Lionel had always shown great zeal in promoting British commercial interests, and, justly or unjustly, had acquired the fame of being intensely anti-American.

From 1911 to 1913 Carden had served as British Minister to Cuba; here his anti-Americanism had shown itself in such obnoxious ways that Mr.Knox, Secretary of State under President Taft, had instructed Ambassador Reid to bring his behaviour to the attention of the British Foreign Office.

These representations took practically the form of requesting Carden's removal from Cuba.
