Durée de service effectif à bord des vaisseaux du Roi

Value of the Information & Strength of the Argument

The value of the information lies in its use of primary sources (naval roles, muster rolls, and pension records) to provide quantitative evidence on a topic often treated qualitatively. The argumentation is solid in that it systematically compares theoretical quotas with actual service data, revealing a significant discrepancy. However, the sample is limited to specific communities (Cancale, Marennes, Martigues) and periods, and the speakers acknowledge the impossibility of full statistical rigor due to high mortality. The reasoning is clear and well-structured, but some claims are based on small numbers and may not be generalizable.

Scientific Rigor, Source Quality, Title Accuracy

The presentation demonstrates rigorous use of archival sources, including roles from the Archives Nationales and the Service Historique de la Défense. The speakers cross-reference multiple types of records to reconstruct careers and mortality. The title accurately reflects the content. The sources are not explicitly cited in the video, but the description mentions the speakers and the context. The analysis is careful, though the informal tone and occasional digressions reduce the perceived rigor. The title is appropriate and does not overpromise.

The title accurately reflects the content, which focuses on the actual duration of service on royal vessels compared to theoretical expectations.

7/10

The presentation is based on original archival research and statistical analysis of a specific corpus (481 men from Cancale), but it is a conference talk with informal tone and some methodological limitations (small sample, survivorship bias). The speakers are historians, but the claims are not peer-reviewed.

Markers derived by PSI from the transcript: the creator did not define chapters.

• 02:00Introduction: the theoretical expectation of one year in four service in Brittany.
• 05:00Presentation of the corpus of 481 men from Cancale and the finding that 80% served less than the theoretical quota.
• 08:00Mortality statistics: half of the men died during the War of Spanish Succession, with 60% dying at sea.
• 12:00Analysis of long careers: even among survivors, average service on royal vessels was only 19%.
• 18:00Transition to the second part: study of the period 1764-1775 using naval roles from Brest, Rochefort, and Toulon.
• 24:00Service duration by port: 4 months at Brest, 6 at Toulon, 9 at Rochefort.
• 30:00During the American War, average service was 18 months, below the theoretical 33%, with half serving only once.
