L. HOLMES HEN THE PRESSURE OF European affairs mounted during W 1795, Spain’s Minister of State, the erratic Manuel de Go- doy, was persuaded to sign the Treaty of San Lorenzo (Pinckney Treaty) with the United States in an effort to neutralize that power in the approaching struggle with the English.
