All of Rommel’s supplies and reinforcements come across those very straits from Italy, and land at Tunis or Bizerta. From there, Rommel can strike out east towards Egypt or west towards Morocco. In the several weeks since the British Eighth Army kicked the crap out of him at El Alamein (which is way, way over there in Egypt) he has been retreating westwards back towards Tunis. In the few weeks since the Americans landed in Northwest Africa, he’s been fighting on a second front to his west. And Rommel has been doing a damn good job of it, as far as Shaftoe can tell from listening between the stentorian lines of the Movietone newsreels, so laden with sinister cheer, whence the above facts were gleaned.
