What is the impression? A lot depends upon that. What we know today as the Baker tent & Wall tent were in use as well as the French Bell tent & Sibley tents as well the wedge & A tent. The CS was chronically short of canvas by mid war and most tentage was nothing more than a large canvas tarp stretched across an upright. The tent cities you see at most re-enactments simply did not exist. The US did quite a bit better but even the US while on campaign didn't haul that much canvas.
