What does the phrase 'on the rhetorical battlefield' mean?

It sounds to me like a description of 2 or more people having a debate, argument or lively discussion that is weak in substance, but that is full of inflated language. Excellent speakers can use rhetoric skillfully to persuade listeners that their position is correct. But it has to be used sparingly and with logical and intelligent substance underlying the argument. Some people are so good at "rhetoric" that the rhetoric itself becomes a battle of wits, or a battle of words. The substance of the argument goes out the window, along with logic and clear thought. It's difficult to describe rhetoric in a few words, but you might find links below as they are found.
