what were the main actions of Dove in chapters 10–12?

Dove is having a bad day––his master, Colonel Smith, has just yelled at him for polishing the wrong saddle. Colonel Smith needed his campaign saddle and Dove polished the parade one instead.

Dove gives Johnny information that the British are planning a campaign for 8 o’ clock tonight, most likely on Lexington and Concord. They believe the campaign will be short––less than a day.
