Benjamin King and Timothy Kuta offer this information in an article available on the US Army Fort Eustis Transportation School website. The article, "Antwerp: Enemy attack on supply lines in Europe 1944 - 1945." was King and Kuta's initial draft of chapter 10 in their book, Impact. The article includes some details that didn't make it into the final published book such as the above dock allocation.
