"Operation Grand Slam", which was launched by Pakistan to capture Akhnoor, a town north-east of Jammu and a key region for communications between Kashmir and the rest of India, was also a failure. Many Pakistani commentators criticised the Ayub Khan administration for being indecisive during Operation Grand Slam. These critics claim that the operation failed because Ayub Khan knew the importance of Akhnoor to India (having called it India's "jugular vein") and did not want to capture it and drive the two nations into an all-out war. Despite progress being made in Akhnoor, General Ayub Khan relieved the commanding Major General Akhtar Hussain Malik and replaced him with Gen. Yahya Khan. A 24-hour lull ensued the replacement, which allowed the Indian army to regroup in Akhnoor and successfully oppose a lackluster attack headed by General Yahya Khan. "The enemy came to our rescue," asserted the Indian Chief of Staff of the Western Command. Later, Akhtar Hussain Malik criticised Ayub Khan for planning Operation Gibraltar, which was doomed to fail, and for relieving him of his command at a crucial moment in the war. Malik threatened to expose the truth about the war and the army's failure, but later dropped the idea for fear of being banned.
