Prussia at Prussian Eylau ?

[waterproof]

We know that Napoleon fought against Russian troops at the Battle of Eylau in Prussia. In the snow and freezing cold. But there was also Lestocq's small corps on the Prussian side. Can anyone tell me where I can find specific information about the strength of the troops and exactly what they consisted of? Which regiments, how many infantry and cavalry. I know that there were only 9,000 men compared to 67,000 on the Russian side. But maybe someone knows of a source where I can read up on this.
