By the middle of November, as Indian intelligence continued to check out further inputs, the pieces of an intricate jigsaw puzzle began to fall into place. Sources say they learnt that the attack would come from the sea and that the Taj Hotel would be a major target. However, it was not known whether this attack would be carried out by planting bombs in the hotel or by terrorists carrying small arms. Indian intelligence assessments were tilting towards bombs being planted and security at the hotel was beefed up accordingly to prevent terrorists from planting bombs inside the premises.
On November 18, R&AW passed on a specific advisory to the Coast Guard, which serves as the Lead intelligence Agency for the coastal area. The advisory asked the coast guard to intensify patrolling and look out for a suspicious vessel, probably of Pakistani origin, which had sailed off from Karachi. While the coast guard began to patrol the area with renewed intensity, the terrorists had an entirely different plan.
According to details available with Indian intelligence and the information given by the terrorist who was picked up by the Mumbai police in an encounter near Chowpatty, the terrorists hijacked an Indian fishing boat, the Kuber, somewhere near Pakistani waters. They beheaded the majority of the boat's crew of six and only allowed one crew-member, Amarsinh Solanki, to live so that he could help them with navigating the boat to Mumbai. The coast guard found a Global Positioning System abandoned on the fishing trawler that was drifting nearly four nautical miles off the coast of Mumbai early on Thursday, November 27 morning, several hours after the terrorist attack began. While the coast guard was looking for a Pakistani or unidentified vessel, the Kuber (registration number 2303) blended in with the thousands of registered Indian fishing vessels out at sea.
This enabled the terrorists to avoid detection and slip into Badhwar park in Cuffe Parade in Mumbai before they began their operations. Most of them got into waiting boats that had been arranged by Karachi-based underworld don Dawood Ibrahim's diesel smuggling network in Mumbai. Arms, ammunition and plastic explosives were quickly transferred to the waiting boats that took the terrorists to the Gateway of India which was the pre-arranged launching pad for the terrorist attack.
What has surprised investigators piecing together the details of the attack is that the GPS recovered from the abandoned trawler, Kuber, had two maps fed into it to aid navigation. One was a route from Karachi that was plotted quite close to the Indian coast, while a return route had also been mapped into the GPS from the Mumbai coast back to Karachi. "We think this was done to give the terrorists some semblance of hope that they would go back home after a successful raid," a top security official told Outlook. The fact that these two maps were fed into the GPS has confirmed that there was some help from people with a naval or army background, and had extensive knowledge of navigation at sea.
