Such a set as you suggest is something I ask to be made for a long time at this forum.
A set with the full 48 figures with all parts of le Grand Armée and one for the russians ofcourse, in a motley looking uniform, add up by everything they found.
And a set of warmcloathed mounted Cossacks only armed with simple lances.
I also hope this set will be made for a while.
Perhaps it will be made. The rear of the chasseurs of the guard box mentions that the set is part of "a line devoted to the retreat of the great army from Russia".
So I think such a set would complement the existing sets.
I know strelets mentionned that they do not plan to make Napoleonics in the near future, but they also said that at the end of 2006 ;-) and these sets will sell well, so I think mr. Derbilov (the sculptor) will come up with some surprises.
I cannot wait for mine to arrive - I am really looking forward to the Cuirassiers and the Russian Dragoons, and really hope they are better than the Saxons and hussars which, while nice and very useable, are not "leading edge" in terms of what (say) Zvezda are delivering.
I too hope that Strelets continue to make great Nap sets, and a retreat box of individuals would be so cool. When I was young I believe "Tradition" did a set in 25/30mm, and they always looked good in Military Modelling.
