"In August, September and October, British commerce lay prostrate and motionless until a protecting and self-defensive system was interposed by our Orders in Council."[179] The first of these ordered reprisals against the new Napoleonic States (November 4th): a week later came a second which declared that, as the Orders of January had not induced the enemy to relax his commercial hostilities, but these were now enforced with increased rigour, any port whence the British flag was excluded would be treated as if it were actually blockaded; that is, the principle of the legality of a nominal blockade, abandoned in 1801, was now reaffirmed.

The carriage of hostile colonial products was likewise prohibited to neutrals, though certain exceptions were allowed.

Also any neutral vessel carrying "certificates of origin"-- a device for distinguishing between British and neutral goods--was to be considered a lawful prize of war.

A third Order in Council of the same date allowed goods to be imported into the United Kingdom from a hostile port in neutral ships, subject to the ordinary duties, and bonding facilities were granted for the re-exportation of such goods to any friendly or neutral port.[180] These orders were designed to draw neutral commerce through our ports, and to give secret facilities for the carriage of our goods by neutrals, while pressing upon those that obeyed Napoleon's system.
The harshest of them was that which encouraged the searching of neutral vessels for certificates of origin--a measure as severe as the confiscation of British property by Napoleon, which it was designed to defeat.

And we may note here that the friction resulting from our Orders in Council and our enforcement of the right of search led to the United States passing a Non-Intercourse Act (December 23rd, 1807) that preluded active hostilities against us.
