On 17 March 1871, there was a meeting of Thiers and his cabinet, who were joined by Paris mayor Jules Ferry, National Guard commander General D'Aurelle de Paladines and General Joseph Vinoy, commander of the regular army units in Paris. Thiers announced a plan to send the army the next day to take charge of the cannons. The plan was initially opposed by War Minister Adolphe Le Flô, D'Aurelle de Paladines, and Vinoy, who argued that the move was premature, because the army had too few soldiers, was undisciplined and demoralized, and that many units had become politicized and were unreliable. Vinoy urged that they wait until Germany had released the French prisoners of war, and the army returned to full strength. Thiers insisted that the planned operation must go ahead as quickly as possible, to have the element of surprise. If the seizure of the cannon was not successful, the government would withdraw from the centre of Paris, build up its forces, and then attack with overwhelming force, as they had done during the uprising of June 1848. The Council accepted his decision, and Vinoy gave orders for the operation to begin the next day.
