However, no attack came. The Spanish social fabric, shaken by the shock of rebellion, gave way to crippling social and political tensions; the patriots stood divided on every question and their nascent war effort suffered accordingly.

These institutions interfered with the army and the business of war, undermined the tentative central government taking shape in Madrid, and in some cases proved almost as dangerous to each other as to the French. The British Army in Portugal, meanwhile, was itself immobilized by logistical problems and bogged down in administrative disputes, and did not budge.
