Based on the information you provided, it seems like you made a mistake in arranging the events in chronological order. To properly arrange these events in chronological order, you need to consider the dates or time periods when each event occurred.

Here is the correct chronological order for these events:

1. American Colonization Society formed
2. Paul Cuffe leads African Americans to Sierra Leone
3. David Walker's appeal

The American Colonization Society was formed in 1816, making it the earliest event on the list. Paul Cuffe led a group of African Americans to Sierra Leone in 1815. Lastly, David Walker's appeal was published in 1829.

Therefore, the correct chronological order should be: American Colonization Society formed, Paul Cuffe leads African Americans to Sierra Leone, and David Walker's appeal.
