Undercover War: Britain's Special Forces and their secret battle against the IRA

Rate this book
When British troops first deployed to Northern Ireland in 1969, to halt the threat of a new rising force - the Provisional Irish Republican Army - they could not have known that the longest campaign in the British Army's history was beginning. While patrols, vehicle bombs and incendiary speeches are the defining memories of the Troubles, the real war was fought out of sight and out of mind. For thirty years, Britain's Special Forces waged a ferocious, secretive struggle against a ruthless and implacable enemy. Harry McCallion offers a unique insight into nearly every major military action and operation in the Province, having served seven tours with the Parachute Regiment, passed selection for 14 Intelligence Company, completed six years with the SAS anti-terrorism team, and joined the Royal Ulster Constabulary, receiving two commendations for bravery during his service. This book is his blistering account of the history of Britain's war against the IRA between 1970 and 1988 - the most murderous years of the conflict - drawn from his own operational experience and backed by first-hand accounts and unpublished documents. From new insights into high-profile killings and riveting accounts of enemy contact, to revelations about clandestine missions and strategies in combating a merciless enemy, Undercover War is the definitive inside story of the battle against the IRA, one of the most dangerous and effective terrorist organisations in recent history.

"I believe it is important to ask how, if it is lawful self defense to kill an Islamist terrorist in Iraq with a drone strike, or to neutralize a wounded threat in London, it could have been anything other than lawful self defense to kill a Provisional IRA terrorist armed with an AK-47, an ArmaLite, or an DShK Heavy Machine Gun in Northern Ireland?"

That pretty much sums up "Undercover War," I think. This book is not, as the blurb says, an "account of the history of Britain's war against the IRA." More aptly, it is a book length argument for how generally fault-less and awesome the Special Forces operatives were in their actions. And it's all told as one long, detailed list of engagements involving U.K. Special Forces during "the Troubles" - the low-key sectarian civil war/anti-terrorist campaign in Northern Ireland between 1970 and 1998.

When I started reading, I didn't really know who the author was (and I was curious to see how that affected my reading of the book). However, it was almost immediately clear where the author's sympathies lie, and a quick search (after reading a good chunk of the book) confirmed that he was indeed himself a former Special Forces operative himself - I was even familiar with some of his other books. Now, I don't necessarily see the author's loyalties as a negative in and of itself, but it does explain his reasoning and approach. Namely that of rebuking efforts to "tarnish" the legal and noble actions and motivations of the Special Forces operatives during the Troubles.

I don't disagree with him in terms of the individuals' actions. As with all military action, military personnel generally aren't themselves held responsible for acts that would be illegal under civilian circumstances. It is, after all, the military's job to execute state sponsored violence. That is also exactly what the Special Forces did in Northern Ireland. Furthermore, I do think that it is important to address, as the author does, how it's kinda fucked up to go after individual soldiers for acts that were sanctioned in one way or the other.

However, I think McCallion kind of misses the real issue for me. Sure, we can argue that individual soldiers and actions were/are lawful under the circumstances (whether in N.Ireland, London, or Iraq), rightly so. For me that's not the real question, waging war is never clean and soldiers are literally paid to commit acts that would land them in prison or worse under any other circumstances. That doesn't make them villains. Nor does it make them heroes as the author implies.

No, the real issue in the case of the Troubles, Iraq, or any other war (whether that be on sovereign nations, wannabe break-out states, the war on drugs, or the war on terrorism) is, should "we" be there at all (with "we" being the state of the relevant state sanctioned intervention/action)? Is the war itself kosher? While the author himself does not allow for any other impression or interpretation, he completely disregards this question and unequivocally considers all enemy combatants as terrorists. Thus justifying treating them as such. Which is fair, it is his opinion - and one I'm largely in agreement with re: the (P)IRA - but I think he's doing the much more complicated situation a disservice in not acknowledging that his terrorists are someone else's freedom fighters. It is, when push comes to shove, definitely worth keeping in mind that the Irish Catholics were a "legally" oppressed minority.

And this, I think, is where the problem with the author's background comes in. He himself has said elsewhere that "[b]eing in a violent atmosphere like that becomes addictive," and that his enemies "were just the enemy that we were fighting and to be quite honest I enjoyed what I did." Moreover, he's said that killing the enemy, "it gave me a kick. For the soldier it's not the same as you murdering somebody. It's addictive." Not only do his own words kind of raise the question that maybe individual soldiers may be more responsible for their own action than he argues in the book, but it also illustrates how, naturally, the author simply cannot allow for anything other than his own black and white interpretation of the Troubles and the Special Forces' involvement in the conflict.

To his credit, McCallion does direct some criticism against structural and operational faults of the U.K. involvement in N.Ireland - especially of the early years when the Special Forces weren't actively involved. But this doesn't really change the fact that "Undercover War" is essentially a bullet-pointed list of engagements from the U.K. Special Forces perspective. It is less interested in providing a history of the Troubles - or even the military engagements during them - and more interested in arguing for the legality of the Special Forces' actions during the conflict.

All the same, McCallion's writing is no-nonsense and crisp, and the book does provide a valuable perspective of the conflict. What really drags the rating down for me is the format. I've repeatedly mentioned the bullet point list structure of the book, and it is a drag. Yes, sure, it's a non-fiction book, but how enjoyable is it to read a 300+ page long list, really!?

Not particularly, say I.

Excellent

Amazing read. Could not put it down. A truly awe inspiring account of the great work, risk and sacrifice of the security forces I evolved in the undercover war against terror before the war on terror. Humbling and proud to be British.

Bought for an ex-Royal Marine during what I’d hoped would be a delightful browse in a bookshop but which actually turned in to a horrific event involving a child wittering in about being bored and me scanning the shelves, giving books a quick flick through before buying them and rushing to find a loo for said wittering child.

For me, the main problem with this book is that it’s essentially a list of events. That necessitated a certain level of existing knowledge of The Troubles so didn’t go in to the history of the inequitable voting system or civil rights movement that would have better helped set the scene ... until around 2 chapters from the end. I think what I wanted was context with the details of the SAS’ involvement overlaid on top of that. I don’t feel like I got that so I’m still in a position of understanding the start (thanks BBC iplayer documentary!) and the 80s/90s (thanks, life!) but not the middle bits.

That said, I think it presented a fairly balanced view of the British army’s behaviour and the various paramilitary organisations though at times the author made direct reference to himself which seemed odd when for the majority of the book he didn’t. I quite liked that comparisons were made with Daesh nowadays; it’s a very different threat and the moral dilemma / threshold was carefully laid out.

What was interesting was discussing the book with said ex-Royal Marine. Neither of us liked the book’s event, next event, next event style of writing. I was deeply miffed that the photos included were of covert operatives (maybe this was written for a niche audience?) rather than providing any context of the effect of The Troubles on the community to add flavour to the events listed.

The stand out moment for me was learning that Bernadette Devlin MP not only called the Home Secretary a liar but also slapped him across the face in the House of Commons. Maybe it was the mood I was in, or maybe it’s several years of the Hostile Environment but I can really feel that fury towards a Home Secretary.

But I struggled with this and skim read it. I’m sure I’ll find what I’m looking for on this topic.

Possibly one of my all time favourite books - I am not a particular fan of SAS books but this was more of a holistic history of Northern Irelands 'troubles' and the actors involved in them. I now not only understand to a far greater degree, their genesis but the response of the UK government and the people of Northern Ireland but look at both very differently.

This book, despite the author's personal involvement, seems to be very unbiased and challenging of all sides. Incidentally, after discussing the book with my friend, an ex-para, I discovered he was actually in the unit joint unit whose activities are eloquently described in the book. Highly recommended!

A nonfiction book which reads like a thriller, this will delight those looking for details on some of the technical aspects of the British Army's involvement in Ulster. This was my first foray into reading about the Troubles, so I admittedly have much more to learn, but my interest was certainly piqued by this book and I look forward to reading more about the subject. The author has a crisp writing style and a reasonable voice, though he of course comes from the British POV. Overall, a great read!

An in-depth book on the role of the intelligence units who operated in N.I.

As someone who has lived through the troubles and witnessed the horror,killings, and bombing that happened in this period or as we ( the general public) knew it as 'the troubles' this book gives a facanating insight of instances I remember clearly, the invaluable behind the scenes and unknown work of our security services. I salute you, the author, and moreover, the brave men on the frontline who helped to bring peace to Northern Ireland.

It was surprising to read how open the British were about killing off suspected IRA targets on sight. Plenty of stories of the SAS identifying a suspect, yelling at them and then shooting them as soon as they turn to see who is calling to them. The IRA killing people for not being Catholic and Loyalist killing Catholics for being Catholic. Ireland was rough.

Very readable but very biased.

Interesting and very readable account of the incredible challenges for the security forces during 'the troubles'. However, the bias in justifying security forces actions when engaging terrorist (and they definitely are terrorist) is clear and difficult to overlook.

Incredibly biased book. Long list of how the SAS / British army influenced and exacerbated conflict during the troubles, followed by the author trying to justify their actions. Calling all deaths at the hands of the IRA as "murder" and conversely never once mentioning the word "murder" when the SAS / british army factions killed civillians.

The conflict in Northern Ireland was an ever-present part of my childhood. My father, a civilian, was bombed three times by the IRA. Posters of IRA and Baader Mienhoff terrorists were in the supermarkets.
This book gives an insight into the dirty war fought on both sides, from someone who was evidently a protagonist or close to being one.

Great read it goes someway into giving allowable information about 14 int and SAS involvement in Northern Ireland some of the things that happened and a lot that didn't happen but certain groups have lead us to believe did.

An excellent read. As a child of the seventies I grew up with th daily news reports of bombings
and shootings.This book gives background to a lot of the SAS and intelligence operations and made me want to learn more about the 'troubles' ,from both points of view.

A very easy read where I managed to finish within a week. A brilliant book giving the reader an insight into what happened behind the scenes, the author certainly appears to try and stay neutral providing the facts and environment of each scenario. Definitely worth it

Very interesting to see an inside look into the UKSF during the Troubles. Most of what I know of those events comes from the Irish Nationalist side so it was very interesting to get a new perspective.

Lived through the period (from afar).This was a fascinating incite into the “troubles”: A warts and all account and not a patriotic spin.
Feel educated having read t. Thank you

Account of the battles of primarily the SAS against the IRA during the N.Ireland troubles. There’s too much “this happened and then this happened”, but when the author seeks to tell a longer story about key events it’s a much easier read.
