The British Library holds several recordings of soldiers from South Asia who fought for the British during the First World War. One of them, Punjabi soldier Mall Singh, was taken prisoner by the Germans in 1915, who used the latest technology to record his voice. Ishleen Kaur of BBC Hindi tells the story behind the recording.
