Thompson was published in 1947 by The Infantry Journal Press, Washington, D.C., and has 236 pages. The book covers the Unit History during World War II, from September 5th, 1944, Brest and Brittany, the November Offensive, the Roer and the Rhine, crossing the Rhine, the Ruhr and the Elbe, to the end of the War in Europe with the occupation of Germany.

My particular copy was signed by Lt. Gen. William H. Simpson himself with a nice note of appreciation to a Colonel Barney Oldfield, who was the Director of the Ninth Army Press Camp.
