Good evening from Tyne Cot Cemetery in belgium, where commemorations have been taking place to mark 100 years since the start of one of the bloodiest battles of world war one. Over three months, british and allied troops fought with german soldiers in what became known as the Battle Of Passchendaele. In the fields around this cemetery, around half a million soldiers on both sides of the war were killed, wounded or went missing. Prince charles, along with the duke and duchess of cambridge, joined 4,000 guests to remember the sacrifice made by so many, in a battle that has come to symbolise the horror of world war one. Robert hall reports. There are few more peaceful places than the gentle slope of tyne cot. Today among its white headstones families looked back across the years to another big push. At ten to four in the morning, less than five miles from here, thousands of men drawn from across britain, france and the commonwealth attacked german lines. The battle we know today as passchendaele would last for over 100 days. We remember it not only for the rain that fell, the mud that weighed down the living and swallowed the dead, but also for the courage and bravery of the men who fought here. Tyne cot overlooks the rolling farmland, streams and woods that were once no mans land. A scar of liquid mud and stagnant, stinking craters. This rare film held by the Australian National archive gives a sense of the struggle to gain ground as more and more men were thrown into the attack. Bert ferns joined the Lancashire Fusiliers with a School Friend at 18. He struggled up slimy duck boards to reach his starting point. We were often taking a quarter of an hour to go a couple of yards, because some of the duck boards were tilted to one side or another. Others were falling into shallows. We got some out and there are some we couldnt get out. The point was, was it worth rescuing two mens lives to save one . Private edward michael, 13th platoon, b company, 44th battalion, australian. Private james munro. 0ne south african infantry regiment. My great Great Grandfather. My great, great uncle, private walter stevenson. Voices and stories from around the world. In the army, members fought and died alongside each other. Bert began his attack here beside the german bunkers that now lies within Tyne Cot Cemetery. The Lancashire Fusiliers made its way up here towards Passchendaele Village and a spot bert later said he would never forget. We came across what would be about 100 yards square of bodies that had been caught in an Artillery Shrapnel attack. They were absolutely massacred. Experiences shared on both sides of the lions. After crawling to the bleeding remains of my colleagues, and fleeing the rage of Military Fire in search of rescue rescue, i waited for death at any moment. You dont know what flanders means. Flanders means endless endurance, blood and scraps of human bodies. Flanders means a red carriage and faithful son death. Tyne cot may not see an event on this scale again, but it has been a place of pilgrimage for a cemetery and is likely to remain so for generations to come. Fora for a century. 0ne one of the most harrowing, heartbreaking stories of the Battle Of Passchendaele is that of 48 year old Harry Moorhouse and his son, ronald, who wasjust 48 year old Harry Moorhouse and his son, ronald, who was just 22. 48 year old Harry Moorhouse and his son, ronald, who wasjust 22. They fought alongside each other in the First World War and then at passchendaele. But they were killed within an hour of each other, both of them, a father trying to save the life of his son. I am joined by harrys great granddaughter, rebecca. An extraordinary story. Just tell us what happened . They we re just tell us what happened . They were a very close family. They were in the same battalion together. In the early hours of the 9th of 0ctober, they were stationed in a little farmhouse in the dark and the rain. It was the worst rain for 30 yea rs. Rain. It was the worst rain for 30 years. The mod was terrible. Their mission was to take belle vue spur, a little ridge nearby. Harry was leading the command. And in the dark and mud, ronald got killed leading his Men Gallantly up the hell. We didnt know he was dead. He was shot. When harry got back to headquarters. , he saw his son had been injured. His sense of loyalty and love was so huge, he insisted on getting a doctor, even though everybody else said, dont do it, it is too dangerous. Within minutes he had been shot by a sniper and died in the arms of his fellow officers. Both of them gone. They had fought together for two years in the war . Yes, they signed straightaway in 1915, well, 1914, as soon as war was declared. Ronald was farming in canada and he came straight back. Harry was a territorial. He went in straightaway as a major. Yes, in the same battalion together. With many of their yorkshire friends. It was a local battalion. Before passchendaele they had been injured and they thought they would get through the war alive . They really did. They fully believed god would look after them. They were very brave men and very gallant men. But they really, truly believed they would be safe. None of the letters written home suggest otherwise. They say, god will look after us, dont worry, we will be fine. Until that point, they had been, even though they had been injured. You have come here today to the commemorative service we have had, attended by Prince Charles and the duke and duchess of cambridge, what did that mean to you . Why did you want to come here . Well, because they must not be forgotten. Today was so extraordinary, because we were surrounded by other people just like us surrounded by other people just like us who had lost members of their families. I never knew these two both their photographs were everywhere and my grandfathers house. They were legends. I am so happy to share the story and so glad everybody is interested. Their sacrifice must not be for nothing. It has to be remembered. If it stops one person not wanting to fight, not wanting a war, then i think perhaps it isa wanting a war, then i think perhaps it is a good thing. This was supposed to be the war to end all wars. It was. It is no such thing because wards have gone on ever since. That hasnt worked. But i think for young people to hear some of these stories and to see places like tyne cot, which is so beautiful and peaceful, it is a good thing that they see this. It is a lovely evening. It has been sunny all day. That is such a far cry from a lot of the Battle Of Passchendaele when it was torrential rain and the fields around here just became a swamp. Was torrential rain and the fields around herejust became a swamp. And men actually drowned in the shell holes filled with liquid mud. It is almost inconceivable. It is inconceivable. I went to look at the little river they had to cross. It is now just a little river they had to cross. It is nowjust a trickle. 0n the night they were making the crossing, it should have been about a foot wide. It was no waist deep in water. But they still went ahead. A lot of men just drowned crossing that little river. Then they slipped back in the mud. It was a ludicrous operation that should have been stopped before it started. Yesterday you went to see the place where harry and ronald died . Yes, that was extraordinary to know that was the actual place. I found it too much. It is a lovely little field. It is green. It is lush. The idea of them struggling up this hill in the dark and the rain, it was too much. Harrys anguish at seeing his son so badly wounded must have been terrible. You have talked about the futility of the battle and how they only gained five miles at the end of three months of horrific fighting. But they felt a huge sense of duty to king and country and empire, but you feel a kind of anger about the water . Well, of course i do because it took my Great Grandfather and his son out of the family. It meant my Great Grandmother was sad for the rest of her life. For the rest of her life she was sad. The lasting effect of that happening to you and the break up, it destroys family life to a certain extent. Yes, i dont believe in war. I less and less think there is any reason to ta ke less think there is any reason to take up arms against anybody. Everybody belongs somewhere and they shouldnt be ta Ken Everybody belongs somewhere and they shouldnt be taken out, they shouldnt be taken out, they shouldnt be taken out, they shouldnt be killed. Rebecca, thank you so much for being with us. Rebecca talking about the horror of the First World War. Perhaps summed up the First World War. Perhaps summed up best buy siegfried sassoon, the poet, i died in hell, they called it passchendaele. Ben brown in belgium. A former royal marine from county antrim, who made bombs for dissident republicans, has been sentenced to a total of 23 years. Ciaran maxwell will spend 18 years in custody and five years out on extended licence. Maxwell spent five years researching, building and storing bomb parts in hides in Northern Ireland, and in woods near his home in devon. Sentencing him, thejudge said his actions had been a Flagrant Breach Of Trust and a betrayal of his position in the armed forces. June kelly reports. Ciaran maxwell appeared the proud commando, posting his Training Exercises on facebook. But even before he passed out, he was the enemy within the Royal Marines, living the most audacious double life. Throughout his military career, he was making bombs for the dissident irish republican group, the Continuity Ira. He was a very accomplished and sophisticated bomb maker who could have supplied these devices over a long period of time to dissident republicans and undoubtedly, i believe, that by being caught now, lives have been saved. Four of maxwells bombs were used by the Continuity Ira in residential areas and two of them went off. No one was hurt. He built 14 bombs and he knew those he was servicing were intent on attacking Police Stations and killing officers. Maxwell had researched over 300 targets. He was from the Northern Irish town of larne and using his military id, he would regularly travel back here secretly carrying bullets and bomb making components. It was near larne that police uncovered the first of a series of hides used by maxwell to store his lethal stashes. These included antipersonnel mines. As a member of the Royal Marines elite 40 commando unit, Ciaran Maxwell was based here in somerset, and this is where he was arrested. For years, without ever being caught, he had been systematically stealing British Military ammunition and adding it to his terrorist arsenal. As well as the locations in Northern Ireland, he had a further network of hides in the west country, close to his home in devon. In all, he had 43 hideaways for his deadly caches. As a teenager, Ciaran Maxwell was badly beaten by a loyalist gang. He was a catholic growing up in a unionist area. As a result, he suffered from post Traumatic Stress disorder. But the prosecution said they did not believe this was at the root of his offending. A former army officer and now Northern Ireland politician doug beattie, is astonished that maxwell got away with his extraordinary double life for so long. We could be looking at loss of life perpetrated at the hands of a serving soldier of the British Military. If we dont have a look at our Security Checks and how we vet people before theyjoin the military, we will have problems in the future. The Ministry Of Defence said all personnel were subject to Security Checks throughout their careers. Ciaran maxwell, the rogue marine, now begins his jail term. 0ur correspondent, nick beake, has been following the sentencing at the old bailey, and gave further details of what was said in court. Thejudge has been giving a the judge has been giving a further insight into this extraordinary double life that Kieren Maxwell was leading. 0n the one hand as a royal marine he vowed to serve his country. But although wiley was creating these bombs knowing full well the Continuity Ira would be able to use them to attack Police Stations and also to kill police officers. The big question lots of people were asking, what was his motivation injoining people were asking, what was his motivation in joining the people were asking, what was his motivation injoining the Royal Marines back in 2010 . Thejudge, mr justice sweeney, said there was insufficient evidence to say maxwell had any sinister motivation in joining the Royal Marines when he did. That said, he said it was clear that he was motivated by sympathies for the dissident Republican Movement and also hostility towards the united kingdom. He talked about him being a prolific and skilful bomb maker. He said that was an asset which was a considerable utility to a Terrorist Organisation like the Continuity Ira. That is some of the thinking behind the decision to jail him for at least 18 yea rs. Decision to jail him for at least 18 years. He said he was a dangerous, dangerous man. He said he was a dangerous, dangerous man. Lets speak to colonel tim collins, a retired army office who served in Northern Ireland. This was a young man who was a catholic, he grew up in a unionist area and he was badly beaten by a loyalist gang. He suffered from ptsd. The prosecution say all of this wasnt at the root of his wrongdoing. Ijust wonderwhat this wasnt at the root of his wrongdoing. Ijust wonder what kind of Background Checks are actually made in relation to new recruits . The Background Checks are really looking for evidence of an individual. We are looking for things that may be in the realm of causing a problem. I think that whilst that is certainly the view the prosecution have, i wouldnt doubt that. It left him vulnerable to the advances of people who have no solution, they are obsolete in society, by which i mean dissident republicans. I fear that indeed a young life has been ruined by his actions. But many lives have probably been saved and this should send a message to people. When he is eventually released from prison he will look back on his wasted life, wasted behind bars, and realise these people have nothing to offer anybody. Would the Army Recruiters have known about the ptsd . No. Its most unusual. The Ministry Of Defence say all military Service Personnel are subject to Security Checks throughout their careers. How often does that happen . Well, it happens on an as needed basis. There was obviously some slackness in terms of his ability to acquire ammunition. That is rare. That needs to be looked at. I think we cant ta ke to be looked at. I think we cant take this out of context. This is a one off. It is an unfortunate case. I think if we draw any particular lessons from this. You may have heard a member of the devolved assembly, who was a soldier, saying that he is astonished that this man managed to get away with such wrongdoing, leading this incredibly involved double life for such a long time . Yes, doug beattie was my sergeant major, so i know him well. Hes right in many respects. We have to look how control stores with ammunition were easy to come by. That has to be looked at. But clearly within this guys lifestyle, because it is notjust subversive offences he is guilty of, he is also guilty of fraud, he is guilty of growing cannabis, this is a devious person who was badly off the rails. Capable of living a double life. I dont think we can draw too many lessons from that. And his mindset in carrying out these acts for the Continuity Ira, four dissident republican group
