One of the documents (Page 1) is rather blurry and difficult to decipher, some guessing has taken place. Also, some ships appear to have been misspelt; I've attempted to correct these.

The documents available to me only cover events up to March 15; other ships may have joined from (or left at) other ports later on. Please scroll down to the bottom of this page for possible, additional ships.

When working with several different documents from 2 sources, as I have done in this case, the details given in one don't always agree with those found in the other, but I've included all of them, again as a basis for further research.

The following ships left Port Said on March 5-1944:

* Norway had a ship by this name, but I have information stating that she acted as Commodore Vessel for Convoy HX 284 which left New York for the U.K. on March 21-1944 and arrived Liverpool Apr. 6, so the Abraham Lincoln mentioned above must have been the American Libery Ship by that name.

The following ships arrived the U.S. around the same time as GUS 33, and may also have been in this convoy:
