Captain Rafiqul Islam (later Major (Retd.), Bir Uttam) commanded Sector 1 from July to December 1971, overseeing one of the war's longest and most sustained guerrilla campaigns. His leadership emphasized discipline, intelligence-driven operations, and deep integration with local communities, turning the challenging terrain of Chittagong and the Hill Tracts into a persistent nightmare for Pakistani forces.
Under his command, Sector 1 fighters executed hundreds of ambushes, sabotages, and raids, significantly contributing to the overall disruption of enemy logistics and morale.Taking Over at a Critical JunctureWhen Captain Rafiqul assumed command in July 1971 following the Sector Commanders' Conference, the war had entered its guerrilla phase. Major Ziaur Rahman transitioned to form Z Force, leaving Rafiqul to manage an already active but expanding front.From headquarters at Harina in the Chittagong Hill Tracts, he inherited approximately 10,000 fighters—including regular defectors from the army, EPR, police, and thousands of trained civilians. The sector's vast area and diverse terrain required meticulous coordination.Rafiqul quickly reorganized sub-sectors, appointing reliable officers and ensuring clear chains of command. His background in the East Pakistan Rifles provided expertise in border operations and small-unit tactics.Core Principles of His Guerrilla StrategyRafiqul's approach to guerrilla warfare was methodical and adaptive:
- Hit-and-Run Tactics → Small teams of 5-15 fighters conducted swift ambushes on convoys, then melted back into the hills or forests. This minimized losses while maximizing disruption.
- Intelligence Reliance → Local tribal informants and scouts provided real-time enemy movement data, enabling precise strikes. Cooperation with indigenous communities in the Hill Tracts was a cornerstone—Chakma, Marma, and others supplied guides, food, and early warnings.
- Sabotage and Economic Disruption → Roads, bridges, railways, and supply depots were primary targets. Mining operations on highways forced Pakistani forces into predictable routes vulnerable to attack.
- Liberated Zones → Early lodgments in the Belonia Bulge were defended and expanded, creating safe areas for training, medical care, and administration.
- Training and Morale → Thousands of recruits crossed into Tripura for Indian-assisted training in weapons, explosives, and survival. Rafiqul ensured propaganda broadcasts and news of successes reached fighters to sustain spirit during harsh monsoons.
- Belonia Bulge Battles — Multiple engagements (June-November) saw forces repel Pakistani counterattacks, maintaining control along the Muhuri River and threatening supply lines.
- Highway Ambushes — Repeated strikes on the Dhaka-Chittagong highway disrupted reinforcements and logistics.
- Raids in the Hill Tracts — Outposts in Ramgarh, Kaptai, Rangamati, and Bandarban faced constant harassment, stretching Pakistani resources thin.
- Support for Operation Jackpot — Though primarily naval, Sector 1 provided ground intelligence and security for commando infiltrations into Chittagong Port.
