The narrative is based on fact and fiction. The names of cities and provinces remain the same. Several names of the characters have been changed. The story is based on an Anglo-Indian family who were residing in India. Mervyn Welsh, the second eldest son of this family, joined the British Army and was in action against Rommel with the 20th Indian Infantry Brigade in Egypt in June 1942. The Brigade lost most of their Infantry and the remnants of the Brigade were sent to Cyprus to form the Crusade Force.
