Deck and Port, or Incidents of a Cruise in the United States Frigate Congress to California is a memoir written by Walter Colton, an American chaplain, and writer, about his experiences during a naval expedition to California in 1846-1847. The book describes the journey of the U.S. Frigate Congress from Boston to the Pacific Coast, including their encounters with Native American tribes, exploration of uncharted territories, and interactions with Mexican authorities during the Mexican-American War. Colton's vivid descriptions of the landscape, wildlife, and people he encountered offer a unique glimpse into the early days of California's history. The book also includes observations on the politics and culture of the time, as well as personal anecdotes and musings on the challenges of life at sea.
