In the post-war Percival Report (written in 1946, published in 1948) the "imminent collapse" of the water supply, estimated by David J. Murnane, the Municipal Water Engineer, on 14 February to occur within 24–48 hours, was highlighted as a direct cause for surrender. According to oral history records, quoted by Louis Allen (author of Singapore 1941–42), Murnane asked for and was promised by General Percival "ten lorries and a hundred Royal Engineers" so he could fix the water supply leaks caused by Japanese bombing and shelling. He never got what he needed: Louis Allen says Murnane got 'one lorry and ten frightened Sikhs'. When confronted again, all that Percival delivered (on 14 February) was one lorry and ten Royal Engineers but it was too late.
