Trudel's Siege by Louisa May Alcott

"Grandmother, what is this curious picture about? " said little Gertrude, or "Trudel," as they called her, looking up from the red book that lay on her knee, one Sunday morning, when she and the grandmother sat sadly together in the neat kitchen; for the father was very ill, and the poor mother seldom left him.

The old woman put on her round spectacles, which made her look as wise as an owl, and turned to answer the child, who had been as quiet as a mouse for a long time, looking at the strange pictures in the ancient book.
