The whole reason for the Civil War was essentially a De-Facto war with the British Empire during it's exisistance at that period in time.
Prime Minister of Britain, Lord Palmerston was attempting to cut the United States
in half by promoting the Confederacy, funding them, offering them Free Trade agreements and Military advisors. People must remember that until the aftermath of World War 2, Britain and the US were arch nemisis'.
infact, Palmerston was ready to assist the confederacy with actual British Military at one point if one of Lee's Battles with the North Resulted in victory for the Confederacy. Palmerston was also assisting the Dutch in shipping slaves to the Confederacy, with East India Company like tacticts.http://en.wikipedia.org/wiki/Henry_Temple,_3rd_Viscount_Palmerston#American_Civil_War
Lord PalmerstonAmerican Civil War
Lord Palmerston's sympathies in the American Civil War (1861-5) were with the secessionist Southern Confederacy of pro-slavery states. Although a professed opponent of the slave trade and slavery, he also had a deep life-long hostility towards the United States and believed that a dissolution of the Union would weaken the United States (and therefore enhance British power) and that a southern Confederacy "would afford a valuable and extensive market for British manufactures".
At the beginning of the Civil War Britain had issued a proclamation of neutrality on 13 May 1861. Lord Palmerston decided to recognise the Confederacy as a belligerent and to receive their unofficial representatives (although he decided against recognising the South as a sovereign state because he thought this would be premature). The United States Secretary of State, William Seward, threatened to treat any country which recognised the Southern separatists as a belligerent, as an enemy of the Union and the North. Lord Palmerston ordered that reinforcements be sent to Canada because he was convinced that the North would make peace with the South and then invade Canada. When news reached him of the Confederate victory at Bull Run in July 1861 he was very pleased, although 15 months later he wrote that "the American [Civil] War...has manifestly ceased to have any attainable object as far as the Northerns are concerned, except to get rid of some more thousand troublesome Irish and Germans. It must be owned, however, that the Anglo-Saxon race on both sides have shown courage and endurance highly honourable to their stock". When news came of the Confederate defeat at the Battle of Antietam a week later, this made Palmerston reject Napoleon III of France's offer to recognise the Confederacy. Palmerston continued to reject subsequent attempts by Confederate supporters to persuade him to recognise the South as he thought the military situation did not warrant it. The tide eventually turned in the United States' favour when the Confederacy was defeated in 1865.
After the seizure of the British ship Trent by a United States Navy vessel under Captain Charles Wilkes in November 1861 to prevent two Southern separatist diplomats making their way to Europe to campaign for support for the Confederacy against the United States, Lord Palmerston ordered the Secretary of State for War to send an extra 3,000 troops to Canada and demanded the release of the two diplomats. Lord Palmerston called Wilke's actions "a declared and gross insult" and in a letter to Queen Victoria on 5 December 1861 he said, "Great Britain is in a better state than at any former time to inflict a severe blow upon and to read a lesson to the United States which will not soon be forgotten." In another letter to his Foreign Secretary the next day, he expected there was going to be war between Britain and the North:
It is difficult not to come to the conclusion that the rabid hatred of England which animates the exiled Irishmen who direct almost all the Northern newspapers, will so excite the masses as to make it impossible for Lincoln and Seward to grant our demands; and we must therefore look forward to war as the probable result.
However, the United States of America's government decided to hand back the prisoners. Lord Palmerston was convinced that the reinforcements he had sent to Canada had persuaded the North to acquiesce.
Lord Palmerston received a law officer's report he had commissioned on 29 July 1862 which advised him to detain the CSS Alabama because it was being built for the South in the port of Birkenhead and it was therefore a breach of Britain's neutrality. Further, the cotton famine in industrial regions of the North was beginning to bite, just at the time when British popular opinion was starting to harden against the Confederates. The ship had left the port after the order had been sent on the 31 July but departed too soon for it to be detained, and it went on to damage Northern shipping. The United States government accused the British government of complicity in the construction of the ship and, in the so-called Alabama claims, demanded damages from Britain. Lord Palmerston refused to pay damages or to refer the dispute to arbitration. It was not until after his death that his successor (Gladstone) agreed to these demands and paid the United States $15,500,000 in gold as damages.
 Electoral victory and death
Lord Palmerston won another general election in July 1865, increasing his majority. He then had to deal with the outbreak of Fenian violence in Ireland. Lord Palmerston ordered the Viceroy of Ireland, Lord Wodehouse, to take drastic measures, including a possible suspension of trial-by-jury and a monitoring of Americans travelling to Ireland. He believed that the Fenian agitation was caused by America. On 27 September 1865 he wrote to the Secretary for War:
The American assault on Ireland under the name of Fenianism may be now held to have failed, but the snake is only scotched and not killed. It is far from impossible that the American conspirators may try and obtain in our North American provinces compensation for their defeat in Ireland.
He advised that more armaments be sent to Canada and more troops sent to Ireland. During these last few weeks of his life, Lord Palmerston pondered on developments in foreign affairs. He began thinking of a new friendship with France as "a sort of preliminary defensive alliance" against America and looked forward to Prussia becoming more powerful as this would balance against the growing threat from Russia. In a letter to Russell he warned him that Russia "will in due time become a power almost as great as the old Roman Empire...Germany ought to be strong in order to resist Russian aggression."
In early October Lord Palmerston caught a chill and a violent fever. His last words were, "That's Article 98; now go on to the next." (He was thinking about diplomatic treaties.) Another apocryphal version of his last words is: "Die, my dear doctor. That is the last thing I shall do". He died at 10:45am on Wednesday, 18 October 1865 two days before his eighty-first birthday. Although Lord Palmerston wanted to be buried at Romsey Abbey, the Cabinet insisted that he should have a state funeral and be buried at Westminster Abbey, which he was, on 27 October 1865. He was the fourth person not royalty to be granted a state funeral (after Sir Isaac Newton, Lord Horatio Nelson, and Arthur Wellesley (the Duke of Wellington).http://www.abjpress.com/tarpb3.html
Webster Tarpley:A NEW ROMAN EMPIRE
It is 1850. Lord Palmerston is engaged in a campaign to make London the undisputed center of a new, worldwide Roman Empire. He is attempting to conquer the world in the way that the British have already conquered India, reducing every other nation to the role of a puppet, client, and fall-guy for British imperial policy. Lord Palmerston's campaign is not a secret. He has declared it here in the Houses of Parliament, saying that wherever in the world a British subject goes, he can flaunt the laws, secure that the British fleet will support him. "Civis Romanus sum, every Briton is a citizen of this new Rome," thundered Lord Palmerston, and with that, the universal empire was proclaimed. .....................
Shortly after that, the British will back Napoleon in his project of putting a Hapsburg archduke on the throne of an ephemeral Mexican Empire - the Maximilian Project. These projects will be closely coordinated with Palmerston's plans to eliminate the only two nations still able to oppose him - the Russia of Alexander II and the United States of Abraham Lincoln. Lord Palmerston will be the evil demiurge of the American Civil War, the mastermind of secession, far more important for the Confederacy than Jefferson Davis or Robert E. Lee. And in the midst of that war, Palmerston will detonate a rebellion in Poland against Russian rule, not for the sake of Poland, but for the sake of starting a general European war against Russia.
But when the Russian fleets sail into New York and San Francisco, when Lee's wave breaks at Gettysburg, when the Stars and Bars are lowered over Vicksburg, the British Empire will be stopped - just short of its goal. Just short - and yet, British hegemony will still be great enough to launch the two world wars of the twentieth century, and the third conflagration that will start in 1991. And as we look forward for a century and a half from 1850, British geopolitics, despite the challenges, despite the defeats, despite the putrefaction of Britain itself, will remain the dominant factor in world affairs.
PALMERSTON'S THREE STOOGES
How do the British do it? How can a clique of depraved aristocrats on this tight little island bid to rule the entire world? Don't believe the stories about the workshop of the world; there are some factories here, but Britain lives by looting the colonies. The fleet is formidable, but also overrated, and very vulnerable to serious challenges. The army is third-rate. But the British have learned from the Venetians that the greatest force in history is the force of ideas, and that if you can control culture, you can control the way people think, and then statesmen and fleets and armies will bend to your will.
Take our friend Lord Palmerston. Pam has the Foreign Office, the Home Office, and Whitehall, but when he needed to start the 1848 revolutions, or when the time will come for the American Civil War, he turns to a troika of agents. They are Lord Palmerston's Three Stooges. But instead of Moe, Larry, and Curly, these Three Stooges are named Giuseppe Mazzini, Louis Napoleon Bonaparte, and David Urquhart. These Three Stooges - far more than the Union Jack, Victoria, the bulldog breed, the thin gray line of heroes, and the fleet - are the heart of what is called the British Empire.
We will get to know Lord Palmerston's Three Stooges better. But first, one thing must be understood. Moe, Larry, and Curly often had to work together on this or that project. But their relations were never exactly placid. [Slapstick episode from a "The Three Stooges" movie is shown to the audience.] You understand: Their stock in trade was infantile violence. So do not be surprised if we find Palmerston's Three Stooges lashing out with slanders, knives, and bombs against each other, and even against their august master, Lord Palmerston himself.
Under Lord Palmerston, England supports all revolutions - except her own - and the leading revolutionary in Her Majesty's Secret Service is Giuseppe Mazzini, our first Stooge. ..........................
Mazzini's American contacts are either proto- Confederates or strict abolitionists, such as William Lloyd Garrison. During the American Civil War, Mazzini will favor both the abolition of slavery and the destruction of the Union through secessionism - the London line. This subversion will be showcased during the famous tour of Kossuth in the United States, next year and the year after. Kossuth will be accompanied by Mazzini's moneybags, the Tuscan Freemason Adriano Lemmi. On the eve of the Crimean War, with Palmerston doing everything to isolate Russia, Kossuth's line will be that the "tree of evil and despotism" in Europe "is Russia." Kossuth will try to blame even the problems of Italy on Russia. Despite Kossuth's efforts, the United States will emerge as the only power friendly to Russia during the Crimean conflict. Kossuth will call for the United States to join with England and France in war against Russia - Lord Palmerston's dream scenario.
Kossuth will refuse to call for the abolition of slavery. Kossuth will get on well with the slaveholders, since he will also be attempting to mediate a U.S. seizure of Cuba, which meshes perfectly with the secessionist program.
Mazzini is the zookeeper for all of these theme parks. But there are other zookeepers, and still more theme parks in the human, multicultural zoo. The custodians are Palmerston's two other Stooges, David Urquhart and Napoleon III.
