    ANALYSIS: Dublin’s Gauleiter was to have sweeping powers which could have meant the liquidation of trade unions and the GAA, writes TOM CLONAN

    SEVENTY YEARS ago this summer, Adolf Hitler’s general staff drew up detailed plans to invade Ireland. In June of 1940, Germany’s 1st Panzer Division had just driven the British Expeditionary Force into the sea at Dunkirk.

    The Nazis, intoxicated by their military victory in France, considered themselves unstoppable and were determined to press their advance into Britain and Ireland. Germany’s invasion plans for Britain were codenamed Operation Sealion. Their invasion plans for Ireland were codenamed Unternehmen Grün or Operation Green.

    Like Operation Sealion, Operation Green was never executed. The Nazis failed to achieve air superiority over the English Channel that summer. By the autumn of 1940 the Battle of Britain had been won by the Royal Air Force (RAF) and Hitler postponed his British and Irish invasion.

    Some military historians also believe that the plans for Operation Green, drawn up in minute detail, may have been a feint to divert British resources away from Germany’s invasion of southern England. However, had the RAF been overwhelmed that summer by the German air force, the Luftwaffe, Operation Green gives a sobering insight into what fate neutral Ireland would have suffered at the hands of the Nazis.

    Operation Green was conceived under the scrutiny of Field Marshal Fedor von Bock. Bock had a fearsome reputation as an aggressive campaign officer – well versed in the concept of Blitzkrieg. Bock had been commander of Germany’s army group north during the invasion of Poland in 1939 and army group B during the invasion of France in May of 1940. Nicknamed Der Sterber, or Death Wish, by his fellow officers, von Bock was ultimately given responsibility for Germany’s planned assault on Moscow (Operation Typhoon) during Germany’s subsequent invasion of Russia.

    In the summer of 1940 however – before Hitler had turned his attentions towards Russia – von Bock was preoccupied with invasion plans for neutral Ireland and assigned responsibility for it to the German 4th and 7th army corps, army group B under the command of General Leonhard Kaupisch.

    If these German army units in particular had reached Ireland’s shores in 1940, the consequences for Ireland would have been tragic and would have profoundly altered the course of history for the Republic and its citizens.

    The German 4th army corps in particular had a brutal reputation in battle and inflicted many civilian casualties as they secured the Polish corridor to Warsaw during the invasion of Poland in 1939. Later in 1941, the 4th army corps, equipped with its own motorised infantry and Panzer tank divisions, would play a crucial role during Operation Barbarossa, Hitler’s invasion of Russia. The 4th army corps, earmarked for service in Ireland in the summer of 1940, conducted brutal operations the following summer as they took Minsk and Smolensk on their advance to Moscow in June and July 1941.

    Had the 4th and 7th been deployed to Ireland in 1940, their tactics would have been brutal and their advance rapid – up to 100km per day.

    The Nazis allocated 50,000 German troops for the invasion of Ireland. An initial force of about 4,000 crack troops, including engineers, motorised infantry, commando and panzer units, was to depart France from the Breton ports of L’orient, Saint-Nazaire and Nantes in the initial phase of the invasion.

    According to Operation Green, their destination was Ireland’s southeast coast where beach-heads were to be established between Dungarvan and Wexford town. Once they had control and airstrips had been established (negligible armed resistance was expected) waves of Dornier and Stuka aircraft would have started bombing military and communications targets throughout the Irish Free State, as it then was, and Northern Ireland.

    In the second phase of the invasion (to start within 24 hours of the first landings), ground troops of the 4th and 7th army corps would have begun probing attacks, initially on the Irish Army based in Cork and Clonmel, followed by a thrust through Laois-Offaly towards the Army’s Curragh Camp base in Co Kildare.

    Their rate of advance would have been rapid, with some units reaching the outskirts of Dublin within 48 hours of landing in the southeast.

    The capital city was identified by the Nazis as one of six regional administrative centres for the British Isles had occupation taken place. Dublin’s Gauleiter was to have sweeping executive powers and would have had instructions to dismantle, and if necessary, liquidate, any of Ireland’s remaining indigenous political apparatus, her intellectual leadership and any non-Aryan social institutions such as the trade union movement or the GAA, for example. Irish Jews would have been murdered en masse.

    Hitler’s generals were aware that their operations in Ireland would have to be self-sustaining given that their troops would be operating far from the continental mainland in Europe’s most western region.

    Adm Raeder described the German force in Ireland as one which of necessity “would be left to its own devices” in order to execute its mission of conquest. Therefore, Operation Green envisaged that German troops here would administer martial law and curfews, commandeering shelter, food, fuel and water from the civilian population. The plans even contained an annex with the names and addresses of all garage and petrol station owners throughout Munster and the midlands.

    This policy of predation on the civilian population would have inevitably led the Germans into direct conflict with civilians as they confiscated livestock, food, fuel and used forced labour to support their advance northwards. As was the case in continental Europe, Irish civilians would have borne the brunt of the casualties in an invasion, either through the vagaries of war, punitive actions by the Germans or through the almost inevitable counter-attack by Britain.

    In military terms, the Irish Army would have been wholly ill-equipped to challenge a German invasion in the summer of 1940. In 1939, there were approximately 7,600 regulars in the Army with a further 11,000 volunteers and reserves of the Local Defence Force, forerunner of the FCA. By May 1940, this number had dropped by 6,000 due to financial constraints. The Irish government’s recruitment campaign only began to bear fruit by the autumn of 1940.

    Had the Germans come ashore in the summer of 1940, they would have been met by an Army with no experience of combined arms combat and capable only of company- sized manoeuvres, involving a maximum of about 100 men. In addition, the Irish Army was poorly equipped, possessing only a dozen or so serviceable armoured cars and tanks. In terms of small arms, the Army did have plenty of Lee Enfield rifles – of first World War vintage – but had only 82 machine guns in total for the defence of the entire State.

    Many Irish units also moved about on bicycles – referred to at the time as Peddling (or Piddling) Panzers. Had they been engaged by the Wehrmacht, the Irish would have been slaughtered.

    Ironically, the Germans were not the only foreign power making plans for the invasion of Ireland in the summer of 1940. In June of that year, Gen Montgomery drew up plans for the seizure of Cork and Cobh along with the remainder of the Treaty ports.

    When Britain’s prime minister, Winston Churchill, became aware of Operation Green, the British military set out detailed plans to counter-attack the Germans from Northern Ireland. Codenamed Plan W, it envisaged Irish Army units regrouping in the Border areas of Cavan-Monaghan and being reinforced by British troops moving south from Northern Ireland. In this scenario, the Irish and British armies would have fought alongside one another to repel the German invasion.

    Had this happened, it is hard to see that widespread casualties, military and civilian, would not have ensued.

    Of course, neither Operation Green nor Plan W were implemented. Ireland survived the war almost entirely untouched by it, thanks largely to its neutral status being respected by the combatants and the crucial role played by the RAF in the summer of 1940.

    Were it not for the sacrifices of the 544 British, New Zealand, Czech, South African, Canadian, Polish, Australian, French and some Irish who fought and died with them during the Battle of Britain, who knows what flag would now fly over Leinster House.

    Somebody was highly imaginative there thinking "Green" meant "Irish".

    "Operation Green" was Hitler's plan to take over Czechoslovakia on March 12, 1938. It was also calle "Case Green" and "Plan Green".

    ("World War II Super Facts" by Don McCombs and Fred L. Worth).

    The closest Hitler would have gotten to Ireland was if "Operation Sea Lion" to invade England was successful. It wasn't.

    That article is almost as ridiculous "got nothing better to do" writing as the "proof" that the Port Chicago explosion of two ammunition ships was actually a test of the Uranium Atomic Bomb.

      The invasion of Ireland was a side plan of Operation Sealion, and probably meant purely as a feint and deception campaign to draw off at least some British troops from the defense of Kent and Sussex.

      Whether "Plan Grün" actually had that name or whether it was planned as a serious operation is a whole different thing again.

        Now I'm going to lie awake at night trying to figure this out. I happen to have a copy of the War Department's Military Dictionary, English-German, German-English, August 5, 1941. It translates the versions of English and German as spoken at that time (69 years ago).

        In the English to German section it does translate "green" to "grün" with an umlaut over the "u".

        But in the German to English section, "grun" (with or without an umlaut) does not appear anywhere. The closest it gets is "Grönland" (umlaut over the "o") for Greenland. Notice that the vowel "o" is used rather than "u".

        Scanning down to a "u" following "Gr" I found "Grund" (no umlaut) for "reason; cause; base; bottom; ground; soil; terrain".

        Other forms of "Grund" appear in Appendix 5 but none relating to a color.

          Grün is Green. Always has been, at least in the past 250 years.

          "Grön" is an old Swedish derivative of the old Middle German base "-gronia" - which describes the color of grass, and from which all three "Grön", "Grün", "Green" are derived.

            No arguments there. There is always the old axiom "Lost in Translation". Besides, what German I know that can be said in mixed company is very small.

              Interesting to read about so far on - seem's Dev's policy of neutrality was completely right, all things considered (It wasn't our war, and we were too puny to effect it's outcome).

              Armed resistance is a forté of the Irish, it would be interesting to imagine how the country would deal with a second occupation considering anyone over 30 at this time could remember living under foreign occupation, and still had the occupiers up in the north-east of the country. Militarily there was no real effort or desire during the build up to the war to arm the nation, but I doubt the locals would have laid down either, peaceful conformity is just not in the DNA.

              I'd imagine an easy military victory followed by endless headaches for the Germans in keeping a lid on tensions. More worrying would have been the latent anti-semiticism in Ireland at the time, fermented mostly by the Church. The 1937 constitution gave unusually strident and equal rights to Jews, which was even more impressive considering the rest of Europe at this time, but the population could often be disdainful of Jewry. I shudder to think what some might have done if given the chance by Nazi-occupiers.

                Being almost quarter Irish myself, (county Kilkenny & county Armagh) I couldn't agree with you more. An Irishman could drink a German under the table with hardly any effort and they would merely disarm them.

                But since I'm also half German/Austrian (with a bit of Welsh and Russian thrown in for good measure - plus a couple of others that I know of) it would be a very interesting contest to me.

                  Crooks,

                  The Brits had fairly well liad oput plans to enter the republic & take on the Germans in the event that something like this happened. This would presesnt Dev with an interesting conundrum. My bet is that after a few pro forma denunciations before accepting help. He might perhaps have sought support from the US in backing some agreement to guarantee British withdrawal upon the cessation of hostilities.

                  Of course, this all presumes Germany actually gets a single unit to Ireland in any shape to fight. My bet is that they could not even get close. Even a handful of RN vessels from Coastal Command & a few destroyres would most likely have been able to cripple any force. And then there's the RAF to worry about...

                    So my question is say that Germany was able to succesfully invade Ireland, could this have been enough to break American isolationism sooner?
