A few days later the pernicious sandfly fever laid hold of me too. I felt as if my skull were full of hot molten lead. The optic nerves were affected and I saw everything through a red haze. Far off, everything was a mess of bloody purple.
We often fell off and stayed lying there for hours. Once a Persian came by and helped us up. I was so feeble and was trembling so much that I was totally unable to pour petrol from the reserve drum into the main tank. The Persian helped it, then I just sank back into the roadside ditch. Thinking was a terrible effort, but sometimes I saw in my mind's eye that grave in Kermanshah where Walter Tbnn had made his last stop on the road to India.
No, no, no, the blood seemed to hammer through my brain
Somehow we managed to pull ourselves together and ride on. I can't explain how, but we did. We ate nothing, sometimes drank nothing for a whole day and then frantically lapped up another salty puddle. We seemed to be becoming less than human, but we rode on and on, as if in a dream, because we felt that it was only by constantly moving that we would beat the crisis. If we lay down, we were lost. Somehow, almost unconsciously, we even took a few photographs.
