When war broke out in 1939, my father, Ed Gallagher, joined the Royal Australian Air Force-he wanted to be "doing something to give Adolf a smack in the eye." In very short order, he found himself flying over the Bay of Biscay in a Sunderland flying boat, transmitting Morse code and searching for U-boats, while often engaged in intense air-to-air skirmishes with German fighter planes. His detailed diaries describe the sometimes thrilling, sometimes boring days of men at war. His letters to my mother, who he had recently fallen in love with, reveal not only his boundless love, but also the unbearable suffering that separation from loved ones brings. After my mother's death, fifty-two years following the end of the war, my sister and I discovered 106 of Dad's letters that Mum had kept in old shoeboxes ... and so began my "PS: Love Me" journey. Ed's toned-down letters, intermingled with his tell-it-like-it-is diary entries, convey a happy-sad tale of love, separation, and loss, and of the horrible waste of war.
