“Determined leadership is vital throughout all echelons of command. Nowhere is it more important than in the higher ranks. Generals who become depressed when things are not going well, who lack the “drive” to get things done, and who lack the resolution, the robust mentality and the moral courage to see their plan through to the end ‐ are useless. They are, in fact, worse than useless ‐ they are a menace ‐ since any sign of wavering or hesitation has immediate repercussions down the scale when the issue hangs in the balance. No battle is ever lost till the general in command thinks it so. … If your enemy stands to ﬁght and is decisively defeated in the ensuing battle, everything is added unto you.”
Field Marshal Montgomery (1887 to 1976), from his memoirs (1958).
Bernard Law Montgomery, 1st Viscount Montgomery, in full Bernard Law Montgomery, 1st Viscount Montgomery of Alamein, of Hindhead byname Monty, was a British Field Marshal and one of the outstanding Allied commanders in World War II.
