We've just returned from filming in France for our documentary. It was a very emotional time for me and it was difficult to balance my feelings for what happened there with the pressures of working!

We started at Etaples Military Cemetery where my great grandfather was buried. Having seen his grave for the first time and knowing that I was the first family member for 89 years to see his grave was too much for me. It's funny how things like that affect you.

I obviously never knew the man and apart from two photos of him, there is nothing else - no family letters, diaries - nothing.

The cemetery itself is a beautiful place and very peaceful. It certainly is an amazing place - very imposing architecture.

From Etaples to the battlefields of Arras. We stopped off in Arras and visited the Place des Heros. It's a beautiful town, very vibrant, with some remarkable old buildings.

On the outskirts of Arras are the battlefields. We did the full tour following the 8th Lincolns route and others, as there are some cemeteries to visit.

Again it was a very emotional time to visit these fields and feel that my great grandfather had been where I stood.

Standing there on April 9th certainly made you think. Maybe in some parallel universe they were reliving that day again. It was a beautiful sunny Spring day - back then it was cold and snowing. It was moving standing in the cemeteries and reading the names and ages. In some of the cemeteries there was a register, which gave further information about those buried. It made very poignant reading. It was strange leaving, espeically when at Etaples; though I'd finally been to places my great grandfather had been and seen where he was buried and paid my respects, I felt awful leaving him behind again. I wanted to take him home with me. I really felt bad as if I was leaving him behind.

We met some charming French people who were able to point us in the right direction when the map reading went awry. We saw plenty of evidence at the side of fields that the battle still keeps turning up in the form of shells and other rusty metals.

At Roeux we grabbed a quick drink at the Cafe des Sports - Sunday in France in the middle of nowhere meant no food! We managed to persuade the owner to feed us with hare pate and bread, as one of the crew was a diabetic. He was a very generous host - despite speaking no English and me basic French we managed to get by.

Though it's been a hectic time cramming all the filming in, we had a fantastic time. Very emotional and moving - proof that those who died are still very much alive in our memories.

Now back in Blighty we've got the task of sifting through all the footage and piecing this documentary together. Hopefully it will be ready for broadcast in June/July and once broadcast will go on sale.
