I was definitely expecting this answer First of all the book name i mentioned above states that Beas was sunkdamaged during the conflict and its news was hid by authorities due to certain diplomatic and internal challenges whose little idea came from that declassified telegram In the second book Story of Pakistan Navy  states that Indian Navy possessed  FrigatesDestroyers at the outbreak of war and only  were paraded after A clash with Brahmaputra of Ghazi is given in Story of Pakistan Navy and War of Twins If you could read out these books then something could drag out A reference which is a matter of this conflict is also portentous
