At the time and ever since, Addington has been criticised for his lacklustre conduct of the war and his defensive posture. However, without allies, Britain's options were limited to defence. He increased the forces, provided a tax base that could finance an enlarged war and seized several French possessions. To gain allies, Addington cultivated better relations with Russia, Austria, and Prussia, which later culminated in the Third Coalition shortly after he left office. Addington also strengthened British defences against a French invasion through the building of Martello towers on the south coast and the raising of more than 600,000 men at arms.
