The MOAA said of Courage and Country: James Shields, More than Irish Luck, “Before
Abraham Lincoln met his end in Ford Theater, he almost engaged in a sword duel to the death on the banks of the Mississippi
with an Irishman named James Shields. This new biography is a psychological history of Shields, an important but often overlooked
figure of the 1800s.”
