Yes, that's right. By order of our new King, Duncan I, not only will we continue the practice of slavery, but we will wage active war against any nation that tries to stop us, especially the nations of CASTLE. By letters of marque and reprisal, we will attack and seize all anti-slavery patrols on the high seas for the crime of piracy, hang all anti-slavery captains and their male officers caught in arms against us, and sell the rest into slavery themselves.
Any soldiers caught trying to liberate slaves by force will be shot instead of captured, especially their officers. Any Communists among them will be hanged, drawn, and quartered, including political commissars, as not being true soldiers. No quarter will be asked and none given to anti-slavery troops. We will defend the right of chattel slavery to the death, and send the hosts of abolition to the dark flames of Hell.
Any nation which wages war against us for the practice of slavery will also have to keep gas masks ready, because we will use chemical weapons against them when necessary. If we take over an anti-slavery nation, its government will be purged of abolitionists, their soldiers indoctrinated or killed, the families of high officials enslaved, and many others possibly enslaved. In more extreme cases, where rebellion is imminent, we will simply exterminate the entire population, down to the last man, woman, and child, and repopulate the land to remove the threat of abolition. We will do whatever is necessary to punish them.
Oh, and all anti-slavery leaders who are part of castle and other such organizations shall be tried as war criminals. That will be the charge on which they are executed.
Consider yourselves warned.
Sir Adam Sinclair, Chancellor of the United Provinces of Lewis with Harris
