Sabotage of Roads and Bridges in Chittagong District

Ambush operations on Pakistani supply lines in Chittagong district and surrounding areas formed a cornerstone of Sector 1's guerrilla strategy during the 1971 Bangladesh Liberation War. The vital Dhaka-Chittagong highway and secondary roads carried essential convoys of troops, ammunition, fuel, and food from Chittagong Port to Pakistani garrisons across East Pakistan.

Mukti Bahini fighters, operating in small mobile groups, repeatedly struck these lifelines, inflicting casualties, destroying vehicles, and forcing the enemy to divert resources to escort duties—severely hampering their operational freedom.The Strategic Importance of Supply LinesChittagong Port served as the primary entry point for Pakistani reinforcements and materiel shipped from West Pakistan. The main highway linking Chittagong to Dhaka (via Feni and Comilla) was the fastest land route for moving these supplies inland.Secondary roads through the Chittagong Hill Tracts and toward Ramgarh supported outposts in the hills. Disrupting these lines isolated Pakistani troops, lowered morale, and prevented rapid response to Mukti Bahini activities elsewhere.Sector commanders, first Major Ziaur Rahman and then Captain Rafiqul Islam, prioritized ambushes as a low-risk, high-impact tactic suited to the terrain.Typical Ambush Tactics EmployedMukti Bahini groups (often 10-30 fighters) used classic guerrilla methods:

Reconnaissance — Local informants and tribal scouts tracked convoy movements, identifying schedules and routes.
Site Selection — Narrow, winding sections of road with high ground on one or both sides—common in hilly areas—provided ideal kill zones. Dense jungle allowed concealment.
Setup — Teams positioned on elevated positions: one group to initiate fire, flankers to cut off escape, and a rear guard to cover withdrawal.
Execution — Attacks began with mines or rocket launchers to disable lead/rear vehicles, trapping the convoy. Automatic fire and grenades followed, targeting personnel and cargo.
Rapid Withdrawal — After 5-15 minutes, fighters melted into the jungle using pre-planned escape routes, often guided by locals.

Night ambushes added surprise, while monsoon conditions slowed enemy recovery.Weapons included captured rifles, LMGs, mortars, and Indian-supplied explosives.Notable Areas and Impact

Dhaka-Chittagong Highway — Frequent ambushes between Chittagong and Feni forced heavy escorts, delaying convoys and exposing them further.
Kumira and Sitakunda Areas — Early ambushes (April-May 1971) by defected EPR and army units disrupted initial reinforcements.
Ramgarh and Hill Roads — Convoys to hill outposts faced constant harassment, isolating garrisons.
Belonia Bulge Approaches — Ambushes supported defense of liberated zones.

These operations destroyed dozens of vehicles, killed/wounded hundreds of Pakistani soldiers, and captured supplies that armed more guerrillas.The cumulative effect tied down thousands of troops for convoy protection, reducing offensive capabilities elsewhere.Challenges and Fighter ResilienceAmbushes risked counter-ambushes or airstrikes if withdrawal was delayed. Monsoons made movement slippery, and limited ammunition required precision.Yet fighters' motivation—fueled by atrocities and local support—ensured persistence. Tribal alliances provided safe havens post-ambush.Legacy of the AmbushesSupply line disruptions in Chittagong contributed significantly to Pakistani logistical collapse by December 1971. They exemplified how guerrilla forces could neutralize superior conventional power through persistence and terrain exploitation.These operations remain a proud chapter in Sector 1's history, showcasing tactical ingenuity and unbreakable spirit.Joy Bangla! Every successful ambush on those supply lines brought Bangladesh closer to freedom.
