This shows that Sandy Rosenthal [Harold's brother] was among a ship of soldiers transported from France to New York in 1945.
Here's a copy of the information about this document copied from ancestry.ca
New York, Passenger Lists, 1820-1957
Name: Sandy Rosenthal
Arrival Date: 18 Jul 1945
Port of Arrival: New York, New York
Ship Name: General Adolphus W Greenley
For context, below are the first pages at the beginning of the ship manifest (for the U.S.S. Gen. Adolphus W. Greeley), preceding the passenger list. They show that the ship left Le Havre [France] on July 10, 1945 and arrived in New York on July 18. They seem to show that over 3,000 soldiers were transported back to the U.S. on this ship during this voyage.
