By 19 October Yudenich's troops had reached the outskirts of the city. Some members of the Bolshevik central committee in Moscow were willing to give up Petrograd, but Trotsky refused to accept the loss of the city and personally organized its defenses. Trotsky himself declared, "It is impossible for a little army of 15,000 ex-officers to master a working-class capital of 700,000 inhabitants." He settled on a strategy of urban defense, proclaiming that the city would "defend itself on its own ground" and that the White Army would be lost in a labyrinth of fortified streets and there "meet its grave".
