I think the Class of 1940 graduated about 67 cadets and nine of them didn't survive the war. Other classes suffered casualties too. At the outbreak of war, these cadets had to lead too many untrained or under-trained recruits. Sometimes whole battalions of men who joined up after Pearl Harbor and fired their 1917 enfields for the first time in actual combat.
One graduate from the Class of 1940 that didn't survive the war was mentioned in the book:
"The War Journal of Maj. Damon "Rocky" Gause"
In one part of the book, it tells of Maj. Gause's escape from Corregidor when it surrendered. He was a US Army Air Corp officer and he made his escape with Filipino Lt. Alberto Arranzaso, a PMA 1940 grad. Arranzaso was wounded by a strafing Japaneseplane while he and Maj. Gause floated/swam away from Corregidor. Knowing he was a dead weight to Maj. Gause, he gave him his money, said something like "my game's up" and plunged underwater, sacrificing himself so Maj. Gause could get away. He knew Gause wouldn't leave him behind and both of them would have eventually perished as a result.
These were good men.
