Sir Stephen King-Hall, The Diary of a U-boat Commander
“ The Straits of Dover were frightful; the glare of the acetylene flares on the barrage showed for miles. Seen from a distance it gave me the impression of the gates of hell, through which we had to pass. I dived, ten miles away, and went through with the tide at a depth of forty metres. Two hours and three quarters of suspense, and at dawn we came up, having passed safely through the great deathtrap. At the moment there is nothing in sight, except a little smoke on the horizon. I am going to dive again till dusk. ”
