On 8 April the United States Navy guided-missile destroyer USS Bainbridge and the guided-missile frigate USS Halyburton were dispatched to the Gulf of Aden in response to the hostage situation, Halyburton carrying two Sikorsky SH-60B Seahawk helicopters on board. A stand-off began on 9 April between Bainbridge, Halyburton, and the pirates' lifeboat from Maersk Alabama, on which they held Phillips hostage.
The lifeboat itself was covered and contained plenty of food and water but lacked basic comforts, including a toilet or ventilation.
Pirate ringleader Abduwali Muse cut his hand trying to keep Perry's knife away from his neck.
Commander Frank Castellano, the commanding officer of Bainbridge, stated that as the winds picked up, tensions rose among the pirates and "we calmed them" and persuaded the pirates to be towed by the destroyer. A fourth pirate, Abduwali Muse, aboard Bainbridge and negotiating for Phillips' release while being treated for an injury sustained in the takeover of Maersk Alabama, remained in custody.When the pirate alarm sounded early on 8 April, Chief Engineer Mike Perry brought 14 members of the crew into a "secure room" that the engineers had been in the process of fortifying for just such a purpose.As the pirates approached, the remaining crew fired flares.On 10 April Phillips attempted to escape from the lifeboat, but was recaptured after the captors fired shots.The pirates then threw a phone and a two-way radio dropped to them by the U. Navy into the ocean, fearing the Americans were somehow using the equipment to give instructions to the captain.
