How Do I Track a Ship's Movements?

Track movements through log position entries and movement records, in date order. A ship's name stays the same while its station and duties change, so dates anchor the movement.

What to check first in this record

Track movements through log position entries and movement records, in date order. A ship's name stays the same while its station and duties change, so dates anchor the movement.

A record you cannot place is not a wasted find. File it with its reference and its filters, and let a later record place it. A search term that returns nothing in one catalogue may return everything in another, because catalogues index different fields. Try the holder catalogue directly.

How do you read what you find?

Period handwriting, period place names and period unit structures all reward a slow reading. Speed is what turns a plausible reading into a wrong one. Look for what the entry does not say, as well as what it says. A missing expected entry, a blank column, or a skipped date is itself a finding. An entry that flatters, an entry that blames, and an entry that is purely routine are written for different readers. The reader shapes the wording.

Common traps in this record type

The most common reason a search fails is a date filter that is too tight. Widen the range by a year on each side before you conclude anything is missing. A search in the wrong language of indexing, modern terms for period records, will fail silently. Use the period terms the catalogue itself uses. A photograph with no caption, a medal with no roll entry, and a story with no dates are all the same problem: a clue without a filter.

How do you work through it step by step?

A useful habit is to write the question at the top of your notes before each step, and the answer, with its reference, underneath it when the step ends. Alternate between personal records and unit records as the steps require. Personal records fix the person, unit records fix the place and the date, and both are needed. Mark every guess with a question mark in your notes, and never let a question mark survive into a finished timeline unexamined.

  1. Fix the ship and the drafting dates from the personal file before opening any ship record.
  2. Open the log for those dates only, and note its reference.
  3. Check crew lists and muster entries against the personal file, name, rating and dates together.
  4. Use action reports and photographs only after the log for those dates has been read.

What to open after this one

Return to the pillar guide when you lose the thread. Pillars exist to restore the shape of a section when detail has obscured it. The end of a guide is a good place to review the timeline for unreferenced entries. Remove them, or mark them, before they harden into facts.

Move from personal records to unit records, or from unit records back to personal ones, deliberately. Each direction answers a different kind of question. If this guide leaves you with one sharp question, it has done its work. Take that question, and its reference, into the next record.
