Thousands of women and children were among those who struggled to leave Singapore just before capitulation on February 15, 1942; their hope was to reach safety. For many that hope was never realized; countless numbers drowned as ships were bombed and sunk on their way to "safety". The "lucky" ones who survived the onslaught of the ships would become guests of the Japanese; many of these would not live to see the end of the war.Two very different women fleeing on those last ships and subsequently interned in camps throughout Sumatra were Margaret Dryburgh, a missionary and teacher, and Shelagh Brown, a secretary at the Singapore Naval Base. Their paths crossed briefly prior to the catastrophic events of 1942 and met again in internment. The "Captives Hymn" composed by Margaret Dryburgh was initially sung by herself along with Shelagh Brown and friend Dorothy MacLeod on 5 July 1942. It has since been sung at services throughout internment and continues to be sung at services all over the world. Music and faith were fundamental to both their lives and Margaret’s creative talents lifted the spirits of everyone during those dark and difficult days.In a remarkable partnership, when the women were struggling to find something new that would lift their flagging spirits, Margaret and fellow internee Norah Chambers produced a "Vocal Orchestra" using women’s voices in place of instruments. The first performance stunned the entire camp; they had never heard anything so beautiful and momentarily made them feel that they were free and floating away with the music.This true account, using personal diaries and family documents traces Margaret Dryburgh and Shelagh Brown’s journey from childhood through to adulthood and internment. Early life shapes adult life and perhaps contributed to their response to captivity which showed courage, tenacity, perseverance and surprisingly, given the appalling conditions, a good deal of humor."May the Day of Freedom Dawn"
