Observation about life
A story's theme is the author's main idea or message. This is usually an observation about life. Many times in young adult fiction these themes revolve around topics such as coming of age, death, belonging, and relationships. Romeo and Juliet has many great themes about how impulsivity can lead to one's death or how a family feud can take away the things that families value most. Moral statements are usually reserved for fables. General subject matter is not a theme but instead a topic. A point of view on a difficult topic is a person's perspective.
The maintenance of a high moral in any army is a critical factor for its performance. At the moment that Washington selected Valley Forge as the location for his army's winter camp; his army was not equally trained and not well equipped as the British were. So selecting that location made easier for Washington's army to keep a good supply source, a shelter for extreme winter conditions and also a close location from British lines in order to make and prevent incursions.
