Today is a good day for those still retaining their brains where Churchill got such a silly idea. It was from Wolseley:
Sir Garnet Wolsel[e]y -- Former Commander-in-Chief of the British Army, SirWinston Churchill -- "In war-time, truth is so precious that she should always be attended by a bodyguard of lies."
Garnet Wolseley wrote in The Soldier's Handbook (1869);
"We are bred up to feel it a disgrace ever to succeed by falsehood . .
. we will keep hammering along with the conviction that honesty is the best
policy, and that truth always wins in the long run. These pretty little
sentiments do well for a child's copy book, but a man who acts on them had better sheathe his sword forever." — prologue to Bodyguard of Lies, by Anthony Cave Brown.
