The passage around this formula
Beyond the convoy arrives having eaten everything it set out with. Adding a second convoy to supply the first does not defeat the limit; it recurses, and the tonnage required grows far faster than the tonnage delivered. This is why the practical answer for two millennia was not better convoys but a different mechanism entirely: draw supplies locally, move along navigable water, or stop.
