“Put your trust in God, but keep your powder dry.”
Oliver Cromwell (1599–1658) English military and political leader
Attributed by William Blacker (not to be confused with Valentine Blacker), who popularized the quote with his poem "Oliver's Advice" http://books.google.com/books?id=JmEaAQAAIAAJ&dq=%22Oliver%27s+Advice%22+Cromwell&q=%22Oliver%27s+Advice%22+Cromwell#v=snippet&q=%22Oliver's%20Advice%22%20Cromwell&f=false, published under the pseudonym Fitz Stewart in The Dublin University Magazine, December 1834, p. 700; where the attribution to Cromwell appears in a footnote describing a "well-authenticated anecdote" that explains the poem's title. The repeated line in Blacker's poem is "Put your trust in God, my boys, but keep your powder dry". <br class="br">Attributed <br class="br">Variant: Trust in God and keep your powder dry. <br class="br">Variant: Put your trust in God, but keep your powder dry.
