单项选择题

The title of the biography The American Civil War Fighting for the Lady could hardly be more provocative. Thomas Keneally, an Australian writer, is unapologetic. In labeling a hero of the American civil war a notorious scoundrel be switches the spotlight from the brave actions of Dan Sickles at the battle of Gettysburg to his earlier premeditated murder, of the lover of his young and pretty Italian-American wife, Teresa. It is not the murder itself that disgusts Mr Keneally but Sickles’s treatment of his wife afterwards, and how his behavior mirrored the hypocritical misogyny of 19th-century America.
The murder victim, Philip Barton Key, Teresa Sickles’s lover, came from a famous old southern family. He was the nephew of the then chief justice of the American Supreme Court and the son of the writer of the country’s national anthem. Sickles, a Tammany Hall politician in New York turned Democratic congressman in Washington, shot Key dead in 1859 at a corner of Lafayette Square, within shouting distance of the White House. But the murder trial was melodramatic, even by the standards of the day. With the help of eight lawyers, Sickles was found not guilty after using the novel plea of "temporary insanity". The country at large was just as forgiving, viewing Key’s murder as a gallant crime of passion. Within three years, Sickles was a general on the Unionist side in the American civil War and, as a new friend of Abraham and Mary Lincoln, a frequent sleepover guest at the White House.
Mrs Sickles was less fortunate. She was shunned by friends she had made as the wife of a rising politician. Her husband, a serial adulterer whose many mistresses included Queen Isabella Ⅱ of Spain and the madam of an industrialized New York whorehouse, refused to be seen in her company. Laura, the Sickles’s daughter, was an innocent victim of her father’s vindictiveness and eventually died of drink in the Bowery district of New York.
Sickles’s bold actions at Gettysburg are, in their own way, just as controversial. Argument continues to rage among scholars, as to whether he helped the Union to victory or nearly caused its defeat when he moved his forces out of line to occupy what he thought was better ground. James Longstreet, the Confederate general who led the attack against the new position, was in no doubt about the brilliance of the move.
Mr Keneally is better known as a novelist. Here he shows himself just as adept at biography, and achieves both his main aims. He restores the reputation of Teresa Sickles, "this beautiful, pleasant and intelligent girl", and breathes full and controversial life into a famous military engagement.
