As I was a stranger to all the lower country, I thought it absolutely necessary for me to come for ward. A thorough knowledge of the country is not easily obtained; such a one, at least, as is necessary to fix upon the most eligible position for forming a camp. The security of the army, the ease and convenience of the troops, as well as to perform the du ties of my office with a degree of reputation, all conspired to make me wish to fix upon the properest ground for the purpose. This it was impossible for me to do, unless I came on before the troops. And I must confess I saw no objection, as your Excellency had wrote me nothing to the contrary, and what I wrote naturally led to such a measure.
