As an historical footnote that I'm sure many around these boards will appreciate, the stoic and laconic American male style of expression also has a literary manifestation. And perhaps the most outstanding work in that tradition are the memoirs of Ulysses S Grant. A couple blurbs that explain what is meant by that:
Faced with cancer and financial ruin, Ulysses S. Grant wrote his personal memoirs to secure his family's future—and won himself a unique place in American letters. Acclaimed by writers as diverse as Mark Twain and Gertrude Stein, Grant's memoirs demonstrate the intelligence, intense determination, and laconic modesty that made him the Union's foremost commander. Personal Memoirs is devoted almost entirely to his life as a soldier, tracing the trajectory of his extraordinary career from West Point cadet to general-in-chief of all Union armies. With their directness and clarity, his writings on war are without rival in American literature.
“The foremost military memoir in the English language, written in a clear, supple style . . . a masterpiece.” —Ron Chernow, in Grant
Reading Hemingway (especially his war novels), it often feels like he is trying to imitate Grant. But it is a poor imitation.
