CAESAR IN ABYSSINIA 179 an anti-aircraft gun, three machine-gun posts, and dis- connected strands of barbed wire entanglements. Three hundred men under a Swiss and his wife. Captain and Mrs. Wittlin, defended the most strategic point on the Franco- Ethiopian railway. Mrs. Wittlin had sores on the legs. Some of the men were down with fever exhaled from the featureless Hawash gorge. Others were out shooting the prolific game. The Greeks were snoozing in the bar under the purple bougainvillea. Along the railway line the dirt-track under mimosa, meant to replace the railway if that were bombed, had only been half-finished. The alternative telephone had been half erected.

Before leaving Addis Margarita had taken the precaution of asking for permission to travel to Harrar. Permits to go from point to point are usual in Ethiopia at any time : in war they are often potent weapons of delay. But
