Hello Angie, I have no knowledge of why he may have gone there but the years that you mention would have been the latter part of WW1, and when you mention that he returned home because of family illness, the war had ended by 11th November 1918 and that possibily was the reason for his return home.And if the story is true he would have been there less than a year. I understand that Clipstone was a training camp. Regards Barbara
