Magic Tree House

Revolutionary War on Wednesday by Mary Pope Osborne, 2000.
The story begins with a prologue that explains things that have happened in the series up to this point, saying that Jack and Annie are currently undertaking a series of missions to four special types of writing for the library at Camelot. These missions cover books #21-24 in the series, and in this book, Jack and Annie need to find a piece of writing that represents “something to send.” To find this piece of writing, they’re off to the time of the American Revolutionary War!


When they arrive, it’s winter, and they find a camp of soldiers nearby. At first, they’re not sure which side the soldiers are on, so they sneak up to the camp to get a look at them. The soldiers catch them spying on the camp, but it’s okay because they’re Patriots, not British Redcoats. The soldiers tell the children that they had better go home, thinking that they’re just ordinary children from their time.
After Jack reads a little further in their book about the Revolutionary War, he realizes that this is December 25, 1776, and that they are about to witness the famous crossing of the Delaware River in Pennsylvania. This was a mission carried out in secret by George Washington and his men. The children listen while George Washington delivers an inspirational speech to the soldiers (“These are the times that try men’s souls.”), but a captain tells them that they had better leave because they don’t want children getting in the way of the mission. However, he asks them to do one favor before they leave. He asks them to take a letter to his family back in Frog Creek. He says that it’s a farewell letter, and they should only deliver it if they hear that the mission has failed and many soldiers were lost. Jack accepts the letter, realizing that this letter represents “something to send.”
Since the children know from their book that the mission will be successful, they can safely keep the letter. Jack thinks that their mission is over, but Annie has other thoughts. She climbs into one of the soldiers’ boats because she wants to spend more time with George Washington. George Washington tries to send the children back, but when the snow gets worse and he considers canceling the mission, the children have to persuade him to continue.

At first, the soldiers think that the children might be enemy spies because they seem to know too much about their mission, and one of them saw Jack writing something down earlier. However, Jack convinces them otherwise when he shows that he copied George Washington’s inspirational speech. He reminds George Washington about what he told his men about perseverance. Jack’s words inspire George Washington to take his own advice.
There is a section in the back of the book with more information about the Revolutionary War and places and people mentioned in the story.
The book is available to borrow and read for free online through Internet Archive.
My Reaction
I didn’t often read prologues to books when I was a kid, and I remember skipping over sections that explained the story background and past events in series that I followed regularly, but in this case, I was glad that the prologue explained the children’s mission. I’ve read books in this series out of order, although I don’t really recommend doing that. The books in the Magic Tree House series are very linear, and there are story arcs that extend over multiple books. If you skip around too much, it can spoil some surprises or disrupt the thread of the story.
I liked how this book introduced children both to the historical event of Washington crossing the Delaware and to the famous speech that he made. The lesson about perseverance was good.
