A watch log is a shared memory of what each post has seen, kept as short factual entries at fixed times with the weather, the sounds, any contact and the state of the warning devices, and read at every handover and reviewed weekly for patterns. It does not prove that a sentry was awake, since a sleeper can fill in a form, so make entries that need something freshly observed and add unannounced checks.
Part of Watch and Patrol Scheduling
Log keeping is the writing down of observations at a watch post so that the next sentry, the roster keeper and the council know what has been seen.
What A Log Is For, And What It Is Not
The parent article lists three purposes: pattern detection, accountability and intelligence, and says an entry of “nothing to report” proves the sentry was awake and checking. The first and third are real. The second is overstated. A pencil can write “nothing to report” in a sentry who is asleep, and an entry made by habit every half hour is copied from the one before. A log is a memory aid, not a lie detector.
What does make a log informative is that each entry contains something that can only be known by looking up now: the direction of the wind, whether a given hilltop is clear, the cloud, a sound heard, the behaviour of a dog or the geese. If the entries stay the same all night in conditions that changed, they are copied.
What You Need
- A bound book or sheets that cannot lose pages, ruled in columns, and a pencil (ink freezes and runs). For making paper see Paper Making; a slate or wax tablet does for short runs.
- A clock source at the post: a watch, a marked candle or hourglass, or the stars. Entries are only as good as the times.
- A way to write in the dark without a light: columns ruled so a sentry can write by feel, and a shaded, low light only when needed (Light Discipline).
- A safe place to keep full books.
Method: Keeping The Log
Step 1: Use a fixed layout.
| Time | Weather and visibility | Wind | Seen or heard | Warning devices | Initials |
|---|
Step 2: Make an entry at fixed times, every half hour at minimum as the parent says. Write the entry after looking at the sky, the wind and the view, not before.
Step 3: Write facts, then guesses, marked as guesses. “Smoke, grey, from the east ridge, started 2140” is a fact; “probably a farmer” is a guess.
Step 4: Log every contact in the six questions (what, how many, where, which way, doing what, since when) and every signal sent or received.
Step 5: Log the handover (Handover Procedures).
Step 6: Spot-check without notice. The roster keeper visits at unannounced times, reads the last entry and checks that it matches what can be seen. Treat a failed check as information about the roster, not as a charge (Sleep Cycle Management).
Step 7: Review weekly. Count and group: movements by day and hour, what passes regularly, which warning devices fire without cause. The parent’s examples of traders passing every 3 days and animals drinking at dawn are patterns of exactly this kind.
Keeping And Using The Books
Store the books in a safe place, because they record who watched when and what was seen. The telegraph articles keep routine message logs for 30 days and emergency traffic records indefinitely (Protocols); the same split suits watch logs, with incidents kept for ever and routine books for at least a season. A log that nobody reads is only a chore, so read it aloud at the weekly meeting.
Common Mistakes
- Pre-filled or copied entries. If three consecutive entries are word for word identical, the sentry is not looking.
- Interpretation in place of observation. The council wants what was seen, not what the sentry decided it meant.
- Writing light at night. A lamp at the post gives the post away.
- Blame for sleeping found by the log. The sleeper is a symptom of the roster.
