As with all of the 90s The Elder Scrolls games, The Elder Scrolls Adventures: Redguard can sometimes be quite confusing, Redguard uniquely being an especially puzzle-focused game. As was done with Arena and Daggerfall, a hint book was a necessary concession to action-oriented gamers, or to players who simply could not solve or did not have the time to solve an especially difficult puzzle.
The omission of "Redguard Companion" from digital copies of Redguard is not such a problem in today's online age, where walkthroughs written or recorded by players are widely available. However, Redguard now being a vintage game, "Redguard Companion" ought to be considered a part of the vintage experience. Furthermore, it is a well-written guide, and contains additional lore for dedicated Elder Scrolls fans to enjoy.

Also, I don't think it says this in either the manual or "The Redguard Companion," so I'll say it here: Press F7 to disable auto-parry. To manually parry, press View.
