Jawaharlal Nehru led Indian government had agreed for a ceasefire in J & K in 1948, but whether General Cariappa was against this cannot be verified.
Several years later, when the first Indian chief of the army, General K.M. Cariappa, began expressing his views on policy matters, Nehru urged him to avoid straying into the areas. Further, Nehru sent Cariappa to Australia as a high commissioner after he retired.
As per a few reports, Cariappa was incredibly disappointed when the Indian government settled for an UN-brokered ceasefire in 1949. He also sent a letter of protest to Nehru but stayed short of quitting. Instead, he took up the responsibility of transforming the army's identity from an imperial to a nationalist one. There is no other credible evidence or source to confirm the authenticity of the reports that General Cariappa disagreed with the ceasefire in Kashmir.
