Operation Grand Slam, launched on 1 September 1965, was Pakistan’s conventional offensive toward Akhnoor, a key communications point in the Jammu region. Designed to regain momentum after Operation Gibraltar faltered, the attack brought armor, infantry, artillery, and airpower into a widening war that India could no longer treat as a contained Kashmir crisis. This episode explains why Akhnoor mattered, how the Chhamb-Jaurian sector offered more room for mechanized action than the mountains, and why command tempo, logistics, and timing became decisive. Grand Slam did not produce the rapid strategic decision Pakistan sought, but it forced India to consider a broader response across the international border in Punjab. The road to Asal Uttar passed directly through this failed attempt to regain initiative.
