Just before midnight on June 1, 1973,
Sea Witch completed her port call at the
Howland Hook Marine Terminal on
Staten Island and departed for sea carrying a load of 445 containers below deck and 285 containers above deck. Under the command of
Sandy Hook Pilot John T. (Jack) Cahill and her
captain, John Paterson, the ship proceeded through the
Kill van Kull towards lower New York Harbor and
the Narrows, passing the
Staten Island Ferry Terminal at 0029 hours on June 2. Directing the
helmsman to bring the ship to a heading of 167 degrees in order to begin transiting the Narrows, Cahill also ordered the ship's speed increased to 13.4
knots, just shy of the maximum permitted harbor speed of 14 knots. With the ship now moving closer to 15 knots due to the effects of a strong 2-3 knot
ebb tide as she passed by the general
anchorage off
Stapleton,
Staten Island, Cahill ordered a course correction at 0036 hours to
port to bring the ship's heading to 158 degrees to bring her in line with the center of the
Verrazzano–Narrows Bridge. The second turn never occurred. When the ship did not respond as expected the helmsman advised the captain that
Sea Witch was no longer responding to steering inputs, Captain Paterson quickly ordered steering control transferred from the
port side steering system to the
starboard system, while Cahill ordered the rudder put hard over to port. Both the captain's and the
pilot′s attempts to regain control of
Sea Witch proved futile, as both the port and starboard steering systems were connected into a single mechanism atop the vessels
rudder post by a faulty "key," a device similar to a
cotter pin, which had failed. Without this small fastener in place all steering control of
Sea Witch was lost, and with the ship rapidly moving out of the channel toward Staten Island Cahill ordered the engines to full
astern, began sounding a series of short rapid blasts on the ship's whistle, and asked Captain Paterson to sound the
general alarm to alert the ship's crew. After attempts by the
chief mate and two
able seaman stationed on the bow to release both of ''Sea Witch's''
anchors failed, Cahill locked the whistle to sound continuously to alert nearby vessels, particularly the nearby
oil tanker of her distress as she continued her turn towards the anchored, fully laden vessel. Less than five minutes had passed from the initial loss of steering control aboard
Sea Witch before she was within a ship's length from
Esso Brussels′ midship, and with the ship still making 13 knots with her engines in full reverse and a collision now unavoidable, Cahill and Paterson ordered the crew off the bow and abandoned the forward
superstructure. Aboard
Esso Brussels, the 36-member crew had roughly two minutes′ warning of the impending collision before the sharply raked bow of
Sea Witch, heavily reinforced for operations in icy harbors, rammed into the tanker at 0042 hours. Rather than crumpling and deforming from the force of its impact with the hull of
Esso Brussels,
Sea Witch′s bow retained its shape as its tore into three midship cargo tanks of
Esso Brussels, locking both ships together and allowing a significant amount of her load of
light Nigerian crude oil to spray onto both ships and spill into the surrounding waters. Sparks from the collision and severed electrical wiring quickly ignited the highly volatile oil and a tremendous explosion occurred, leaving both ships afire and wreathed in a large and growing pool of burning oil. As the crew of
Esso Brussels made their own attempt to abandon their ship, the crew aboard
Sea Witch mustered in her aft superstructure, where they attempted to lower her aft
lifeboats. Heavy smoke, heat, and a growing number of shrapnel-laced explosions from several burning containers filled with aerosol cans frustrated their initial efforts, and as the rapidly spreading burning oil slick enveloped the ship the effort was abandoned and the crew took shelter in a cabin equipped with a half-inch fire hose to await rescue. During this time, the still-engaged engines of
Sea Witch began to pull the two ships into the center of the Narrows, where the burning pool of oil sent flames high enough to scorch the bottom of the Verrazzano–Narrows Bridge above the water's surface. Fortunately, the anchor chains on
Esso Brussels parted at this point allowing both ships to pass under the bridge quickly, preventing the steel from suffering significant heat damage. Propelled by the outbound tide and the engines of
Sea Witch, the two furiously burning ships proceeded into outer New York Harbor, where they ran hard
aground in
Gravesend Bay. ==Rescue==
