Map of BangladeshInitial planning of Operation

Nine crewmen decided to take control of the submarine PNS Mangro (which was commissioned first on 5th August, 1970) . However, their plan was disclosed causing them to flee from death threats made by Pakistan’s Naval Intelligence. Out of the 9 crewmen, one was killed by Pakistan Naval Intelligence, but the others managed to travel to the Indian Embassy in Geneva, Switzerland. From Geneva, embassy officials brought them to New Delhi on April 9, 1971 where they began a program of top-secret naval training.

After initial training in Delhi under commander Sharma and Brg. Gupta, from April 25 to May 15,1971, the 8 Bangladeshi submariners started recruiting volunteers from different Mukti Bahini reception camps to form a strong naval commando unit with help of Indian Navy.

Simultaneously, Indian Commander Bhattacharyya, Major Jalil and Colonel M. A. G. Osmani in collaboration with top regional commanders established a secret camp codenamed C2P, in Plassey. Meanwhile, the Mukti Bahini launched several operations in Satkhira, Tangail and Barisal. Guerrilla attacks were carried out on targets in Dhaka by a crack commando group trained by Major ATM Haider (ex-SSG commando of Pakistan Army), and the simultaneous mining and damaging of ships in Chittagong, Mongla, Chandpur, and Narayanganj on August 15,1971 . This became known in international media as “Operation Jackpot”.

By the last week of May, 1971 the volunteers joined the Plassey Camp for training. Initially only 300 volunteers were chosen. Later, an additional 200 commandos were trained in the Plassey training camp. The Camp Commander at C2P was Commander M. N. Samanth, MVC. Training Coordinator was Lt. Commander G.

Importance of the Naval commando training program :

India and Bangladesh Military high command gave an extra importance to the Naval Commando Operation. Special care were taken on training. The naval commandos received the best food and military rations compared to the other Mukti Bahini.They were given extra allowances shared same medical facilities as the Indian Navy.MARCOS

The naval commando training camp was often inspected by Chief of Indian Naval Staff Admiral Nanda, Commander of Armed Forces of Bangladesh Col.M.A.G.Osmani and Commander of Eastern Theatre Lt.Gen.G.S.Aurora. During these inspections, officers personally talked with trainee commandos and asked about their training development and discussed their personal and social problems .

In a discussion on 15th June, 1971 at Plassey with trainee commandos, Admiral Nanda said that "Our aim is not only to destroy the ships in ports but also create an international opinion that foreign ships are not secured in East-Pakistan sea port, so once are successful in our operation foreign countries will not send their ships and supply to East Pakistan ports".

The second target was to destroy ships as well to cut the cable by which ships are berthed with anchorage post. If the cables are demolished in the mined ships, then the power of the tide shall push the ship to sink horizontally in a port and if few ships sink in a port horizontally ,then the ports will be damaged for years together. Due to this particular reason, necessary training was given to the commandos as to how to put a cable cutting charge on a berthed ship. The instructors made it very clear to the trainees that ships are to be mined as well as the cables demolished along with the ships.

The training programme was almost 15 to 18 hours daily . The course included swimming, night swimming, survival training, under water demolition, night demolition, object demolition training with strong foundation like bridge or big building, using limpet mines on ship like objects, hand to hand combat etc. During training commandos were divided into 8 Grades according to their training results. The best commandos were in Grade A and as per the training result they were posted till Grade H. The commandos were selected for operation not only based on their results but also on their origin of home district. Information on river tides, weather and East Pakistan naval infrastructure and deployment was collected through the Indian Military report and Mukti Bahini. Selected commandos were sent from C2P to forward bases in Tripura and West Bengal, where a final briefing was given to them.

By mid-July 1971, the first batch of commandos were ready for operation.

Final Briefing and Commander Selection for Mongla Port

For Mongla Operation, 60 of the best commandos were selected from Khulna region and they were transported from Plassey to Barackpur Cantonment on 26th July, 1971. After resting for few hours in Barackpur Cantonment, the commandos were transported to Port Canning Matler.

On 27th July at around 1-30 P.M, the Commandos arrived in Port Canning Matler where 200 C and C Specially trained land commandos were per-stationed.
