"Give immediate instruction to all your posts in said territory, under your direction, at no time and on no pretence to hoist, or suffer be hoisted, the English flag"

This quote by Zebulon Pike is instructing those in charge of posts in a particular area to ensure that the English flag is not hoisted or allowed to be hoisted at any time or under any circumstances. This suggests that the territory in concern is not under English control and that the English flag must not be flown as a sign of sovereignty. Pike is emphasizing the value of following this instruction, as it is a direct order from him. He is also stressing the value of following this direction right away, as any delay could be viewed as a sign of disrespect or defiance. This quote is a pointer of the importance of following orders and appreciating the sovereignty of other nations. It likewise works as a warning to those in charge of posts in the area in concern to be vigilant and to make sure that the English flag is not raised or allowed to be hoisted.
