Lords of Finance by Liaquat Ahamed (pg. 204)

Convinced that finance had become war by other means, officials resorted to military analogies. Prime Minister Poincaré declared in the National Assembly that he had in his possession a secret document outlining a “plan for an offensive against the franc,” which Stresemann was supposed to have circulated to a conclave of German bankers at the Hotel Adlon. The “attack” was to be “launched” from Amsterdam, where German business houses had allegedly accumulated a reserve fund of 13 billion francs. It was reported in a U.S. newspaper that the Lutheran pastors of America had received a letter suggesting that they urge their flock to dump francs in order to “assist in bringing France to its knees.” The French were then, and would remain for many decades, obsessed with the specter of foreign speculators.
