In the fateful night of 1 to 2 July Shomarey I never asked how the ship, but the morning was a little surprised by the disappearance of the "Echo". He had not even tried to find out the reasons for its disappearance. Other ships that accompanied the frigate, are still a few days ago. A caravel "Echo" has continued to follow the right course, "Medusa" was moving in the same direction, but closer to the shore. Shomarey ordered to measure the depth of the seabed and not feeling for him, thought he could freely steer the ship to the shore. Despite numerous warnings the crew that the ship is in the area Arguinskoy shallows, Captain "Medusa" continued to lead the frigate to the coast. And the fact that it was a dangerous place, and pointed to the surrounding landscape, and change the color of the sea.
