Campe's Kleine Kinderbibliothek
A new purchase, once again inspired by a reference in Marwitz's memoirs (Seite 77), apparently he read this whilst stuck in Nieszawa in Poland without German books or newspapers. A present for his brother that fortunately he had been unable to deliver.
A lovely little book, full of poems, prayers and short stories, all you need to correctly bring up a Prussian. More of an insight into the way people thought in that time and place than any historian could tell me, I like to imagine.
