"I wrote in my diary a lot of detail on everything, like feeling scared on the exercises and everyone having to take their shoes off so their feet could be examined. I was running across Dartmoor and as it was so boggy, I was falling over, getting up and falling over again while there was firing going on over my head.
"From my diary, I pulled out what felt dramatic and the important movement ideas. I ended up with lists and lists to work with and that's when I took it into the studio with the dancers. So, for instance, elements of falling over and getting back up feature in the show."
"I did feel the pressure of getting it right as from early on, I realised how precise soldiers are with their work and if you get something wrong, that's what they keep talking about. They'd talk about movies that got army life completely wrong or the ones that got it right."
Performing 5 Soldiers is Birmingham-based Rosie Kay Dance Company, Kay's international award-winning dance theatre group. It features the choreographer's trademark style of intense physical and athletic dance. It's also an intimate view of training that prepares troops for the sheer physicality of combat, the possibility of injury, and the impact of conflict.
"I felt I needed to get under the skin of these soldiers, to feel what they feel," Kay tells me. "It was important to me that the dancers also spent time with the military and talked with soldiers to understood them and make the performance richer."
"We weren't invaded so we don't feel it on a day to day basis," adds Kay, "but from spending time with the Army, I was struck by the level of injury. There has been a lot in the news about World War One remembrance but we are in danger of forgetting the legacy of these wars - we still don't totally understand post traumatic stress. There are issues right now and the military is trying to modernise and come to terms with itself to become an Army for the future.
"Many soldiers have come up afterwards and said that parts of the performance made the hairs on the back of their necks stand up, but the show also has very complex choreography that earns the dancers respect.
"We have a responsibility to understand what it is we ask our soldiers to do, and how it affects them. We aim to make an impact with this tour and make people see conflict and the repercussions of war in a new way."
The show is supported by Arts Council England and the Army Benevolent Fund, The Soldiers' Charity, and will feature a series of events and post-show talks around performances.
