There's a picture here.
I had to check the text, where I found that was what Tolstoy had written -- but he was writing the book in the 1860s and obviously hadn't done his research!
On the other hand, it isn't clear exactly what the waltz was in the early decades of the 19th century. Most references make it clear that it was like a regular line dance of the time but with a section in which the couple turned together, in one another's arms. It also kept the couple together throughout, which was different to the usual country dance in which the dancers moved among others.
