The cost of a couple of tons of flour or grain dust is irrelevant at this point. They've captured so many thousands of ton of grain that they can't usefully account for it all before they have to fight off the army trying to take their recently acquired city.

With good enough Administration rolls, the PC could manage to get maybe several dozen sailors acting as foremen for an unknown number of recent POWs and/or local slaves to work for them during the 12 hours they have. But grinding sawdust to save the cost of a couple of tons of grain dust is insanely low on the priority scale. Far better to have all available workers move artillery from the coastal forts to the land walls, collapse houses near likely breach points, erect obstacles around the gates, etc.

That means that two tons under combat conditions is not going to be enough for such a big cloud. On the other hand, a unit of thousand men might only occupy 20 yards by 50 yards when massing for an assault through a breach and an explosion of half the volume above would tear the heart out of one (and probably everyone nearby)
