Bold at the council board
But cautious in the field.
~ Dryden

I know him a notorious liar,
Think him a great way fool, solely a coward.
~ Shakespeare

Cowards fear to die; but courage stout,
Rather than live in snuff, will be put out.
~ Sir Walter Raleigh

Cowards die many times before their deaths;
The valiant never taste of death but once.
~ Shakespeare
