 After the defection of Pakistan Navy's Bengali officers and sailors to India, the Eastern Command (Pakistan) was under intense pressure to counter the insurgency and the advance of the Indian Army towards East Pakistan on three fronts.The Yahya administration insisted the Navy attempt to reinforce the naval defence of the East while the Navy NHQ objected to the idea of deploying "Ghazi" in the total absence of a seaport, straying away from their original plan.Many senior commanders had felt that the deployment of "Ghazi" was highly dangerous and impossible to achieve by sending the obsolete submarine behind enemy lines but deployment came when it became apparent that the war was inevitable.
