by John Marshall, Olivera v. The Union Insurance Company…
“ The application of force is not more direct on a vessel stopped in port by an embargo, than on a vessel stopped in port by a blockading squadron. The danger of attempting to violate a blockade is as great as the danger of attempting to violate an embargo. The voyage is as completely broken up in one case, as in the other, and in both the loss is produced by the act of a sovereign power. There is as much reason for insuring against the one peril as against the other ”
