Roger B. Taney,
Cushing v. Owners of the Ship John Fraser…
“ It is true, that the John Fraser was the res or thing which struck the James Gray, and did the damage. But the mere fact that one vessel strikes and damages another, does not of itself make her liable for the injury; the collision must in some degree be occasioned by her fault. A ship properly secured may, by the violence of a storm, be driven from her moorings and forced against another vessel, in spite of her efforts to avoid it. ”
