A very fascinating painting had been shown during the exhibition about the Black Duke of Brunswick this year - it depicts the storming of the "Burgtor" (Castle gate) of Lübeck by troops of Bernadotte against the troops of the younger Brunswick.
The painting shows a lot of interesting uniform details - e.g. the different colors of french infantry uniforms of the early imperial period.
Although the accompanying texts are in German, you may judge the images by yourself (just click on the thumbnails and download the larger images if needed; if you switch to English (via the small flag) you may have an understandable navigation.
If you follow the link given below you will be directed to the section of the uniform portal with 8 images of the painting.
All the best
