:00:28. > :00:31.I'm here in the city of Mons - where the first big battle involving
:00:32. > :00:35.Behind me is the St Symphorien war cemetery, where final preparations
:00:36. > :00:43.are underway for a special ceremony of remembrance later this evening.

:01:14. > :01:23.and the Duke and Duchess of Cambridge were there, too.
:01:24. > :01:31.We were enemies more than once in the last century, and be sold at
:01:32. > :01:35.those who died to give us their freedom.
:01:36. > :01:37.In Scotland, Prince Charles and the Prime Minister David Cameron
:01:38. > :01:39.were at a special service at Glasgow Cathedral, which
:01:40. > :01:42.remembered the part the Commonwealth nations played in the war.
:01:43. > :01:44.In Kent, Prince Harry unveiled a memorial arch in Folkestone -
:01:45. > :01:48.where a parade followed the route taken by millions of soldiers who
:01:49. > :01:55.marched to the harbour to begin their voyage to France in WW1.
:01:56. > :01:58.Kids all over the UK have been learning about what
:01:59. > :02:01.happened 100 years ago - and why it's so important to remember those
:02:02. > :02:25.There have only been two World Wars. I think it is really important. It
:02:26. > :02:32.is quite scale, I would not want anyone I know to go through that. I
:02:33. > :02:44.think it is important that we remember this. Here in Mons, some
:02:45. > :02:48.children are preparing to deliver a song that decomposed themselves. You
:02:49. > :03:00.only have a fewer errors, how are you feeling? -- a few hours. We are
:03:01. > :03:08.nearly there and it is so exciting. Tell us about the song. I was
:03:09. > :03:15.inspired by the whole experience, and it is all about hope and peace.
:03:16. > :03:27.I think it is going to be a good song to commemorate this event. And
:03:28. > :03:32.you must be proud of these guys? They have written the perfect song
:03:33. > :03:39.for this very daunting occasion. It is going to go very well and we are
:03:40. > :03:45.really excited. You have done a lot of research, read some postcards?
:03:46. > :03:49.How did you feel? It made us think about what it was like. We never
:03:50. > :03:55.knew about some of the horrible things that happened. It opened our
:03:56. > :04:00.eyes. It was horrible to think that they had to keep positive, and about
:04:01. > :04:14.how it got, but that helped us. Good luck. I look forward to hearing it.
:04:15. > :04:17.Well a lot is happening today to mark the centenary.
:04:18. > :04:20.Yes Ricky, the services and ceremonies will continue this
:04:21. > :04:24.Here at Westminster Abbey in London, from 10pm there will be a special
:04:25. > :04:29.And while that service is going on, all over the UK public buildings,
:04:30. > :04:31.businesses and people in their homes will turn
:04:32. > :04:34.off their lights for an hour, to leave just a single candle burning.
:04:35. > :04:37.In the cathedral behind me, at 11pm, there'll be a special moment to
:04:38. > :04:54.mark the exact time Britain declared war on Germany in 1914.
:04:55. > :04:59.That is all from me. You can help the song later on at 6:30pm.
