The black merchant ship was oblivious to the Coast Guard patrol craft, or so it seemed to the Canadians. Had they tracked the radar set more closely, they would have noticed that the American ship was both accelerating and subtly changing course.

“Why won’t they respond?” muttered the helmsman, growing weary of Hopkins’s unanswered radio calls.

“We’ll get their attention now,” Weber said. The captain walked to the console and pressed a button that activated the ship’s marine air horn. Two long blasts bellowed from the horn, the deep bray echoing across the water. The blare drew the men on the bridge to silence as they awaited a response. Again, there was none.

There was little more Weber could do. Unlike in the United States, the Canadian Coast Guard was operated as a civilian organization. The Harp’s crew was not military trained, and the vessel carried no armament.

The helmsman eyed the radar screen and reported, “No reduction in speed. In fact, I think she’s still accelerating. Sir, we’re coming along the ice pack.” Weber detected a sudden urgency in his voice. While focused on the merchant ship, the helmsman had neglected to track the hardened pack ice that now flanked their port side. To starboard, the steaming merchant ship rode just a dozen meters away and had drawn nearly even with the patrol craft.

Weber looked up at the high bridge of the Atlanta and wondered what kind of fool was in command of the ship. Then he noticed the bow of the freighter suddenly veer toward his own vessel and he quickly realized this was no game.

“Hard left rudder,” he screamed.

The last thing anyone expected was for the merchant ship to turn into them, but in an instant the larger vessel was right on top of the Harp. Like a bug under the raised foot of an elephant, the patrol boat madly scrambled to escape a crushing blow. Frantically reacting to Weber’s command, the helmsman jammed the wheel full over and prayed they would slip by the bigger ship. But the Atlanta was too close.

The side hull of the freighter slammed into the Harp with a deep thud. The point of impact came to the boat’s stern, however, as the smaller vessel had nearly turned away. The blow knocked the Harp hard over, nearly capsizing her as a large wave rolled over the deck. In what felt like an eternity to the stricken crew, the Coast Guard craft gradually rolled back upright as it fell away from the bristling sides of the merchant ship. Their peril was not over, however. Unknown to the crew, the collision had torn off the vessel’s rudder. With its propeller still spinning madly, the patrol boat surged straight into the nearby ice pack. The Harp drove several feet into the thick ice before grounding to a sudden halt, flinging the ship’s crew forward.
