Nor was Pinckney's conduct at Madrid likely to make Monroe's mission easier. Two years before, in 1802, he had negotiated a convention by which Spain agreed to pay indemnity for depredations committed by her cruisers in the late war between France and the United States. This convention had been ratified somewhat tardily by the Senate and now waited on the pleasure of the Spanish Government. Pinckney was instructed to press for the ratification by Spain, which was taken for granted; but he was explicitly warned to leave the matter of the Florida claims to Monroe. When he presented the demands of his Government to Cevallos, the Foreign Minister, he was met in turn with a demand for explanations. What, pray, did his Government mean by this act? To Pinckney's astonishment, he was confronted with a copy of the Mobile Act, which Yrujo had forwarded. The South Carolinian replied, in a tone that was not calculated to soothe ruffled feelings, that he had already been advised that West Florida was included in the Louisiana purchase and had so reported to Cevallos. He urged that the two subjects be kept separate and begged His Excellency to have confidence in the honor and justice of the United States. Delays followed until Cevallos finally, declared sharply that the treaty would be ratified only on several conditions, one of which was that the Mobile Act should be revoked. Pinckney then threw discretion to the winds and announced that he would ask for his passports; but his bluster did not change Spanish policy, and he dared not carry out his threat.
It was under these circumstances that Monroe arrived in Madrid on his difficult mission. He was charged with the delicate task of persuading a Government whose pride had been touched to the quick to ratify the claims convention, to agree to a commission to adjudicate other claims which it had refused to recognize, to yield West Florida as a part of the Louisiana purchase, and to accept two million dollars for the rest of Florida east of the Perdido River. In preparing these extraordinary instructions, the Secretary of State labored under the hallucination that Spain, on the verge of war with England, would pay handsomely for the friendship of the United States, quite forgetting that the real master of Spain was at Paris.
