Gaps and conflicting sources
Notes from the research chronology for the years this era covers.
Spanish rule · German rule, 1886–1914
Years with no event found: none. Every year from 1886 to 1914 has at least one sourced event.
- Thinnest years: 1888, 1895 and 1902 rest mostly on single mission or compiled sources. 1902 has one solid row (Kosrae Christian Endeavor) plus two “weak” Wikipedia-mirror rows.
- Thinnest islands: Kosrae’s German-era events come almost entirely from the COM-FSM Kosrae outline, a compiled teaching page that warns its details differ from other sources. Chuuk has nothing between 1903 and 1907.
- Unresolved conflicts:
- Yap’s first governor: Manuel de Elisa (Elisa Vergara) or Mariano Torres de Navarro. Both names come from COM-FSM pages.
- Luis Cadarso’s posting: Cabello and MicSem put him on Pohnpei from 1887 to 1891. The Revista General de Marina (Nov 2025) puts him in the Western Carolines (Yap) from 1887 to 1890 (RGM).
- Boeder’s start: 1909 (dewiki) or 1910 (MicSem).
- Start of German Capuchin rule: 1903 (COM-FSM) or the decree of 7 Nov 1904 (MicSem). The likely reading is that the first German friars came in 1903 and the formal transfer followed in 1904.
- Saipan coming under Yap: April 1906 (dewiki) or the 27 Feb 1907 decree (dewiki; Habele says 1907).
- Yap cable: laid 1904 (atlantic-cable.com), opened 1905 (MicSem).
- Not found:
- Exact October 1914 landing dates for each island.
- A dated Liebenzell Mission arrival in Chuuk. MicSem says only “early 1900s” (MicSem).
- German-era copra export figures.
- The Woleai 1907 death toll.
- Any Spanish post in Chuuk.
- Partly consulted: MicSem’s Yap page is cited at the
www.micsem.org/pubs/books/catholic/yap/address, because themicsem.org/pubs/books/catholic/yap/index.htmaddress shows a verification screen instead. The last ~20–30% of the MicSem Pohnpei and Chuuk pages was not consulted for this site.
Japanese rule · World War II, 1914–1945
Years with no event found:
- None. Every year from 1914 to 1945 has at least one sourced row.
- Thin years: 1916 has only naval post-office records (weak); 1925 has only branch-head appointments; 1928 has only one weak school-founding row.
Notes on conflicts and gaps:
- Kosrae: none of the sources used here gives the October 1914 occupation date. It was never a separate branch office; it came under Ponape, then the Eastern Branch from 1943.
- Spanish Jesuit return: March 1921 (Jesuit Conference of Asia Pacific) or 1922 (MicSem).
- First Ponape raid: 14 February 1944 (Pacific Wrecks) or 15 February 1944 (Japanese Wikipedia). Pacific Wrecks lists missions to 6 February 1945; Japanese Wikipedia says major attacks ended in May 1944.
- Yap surrender: 2 September 1945 (JACAR, start of occupation) or 5 September 1945 (Pacific Wrecks, Eto aboard USS Tillman).
- Eastern Branch merger: 5 November 1943 (JACAR) or 4 November 1943 (one Japanese Wikipedia entry).
- 49th IMB on Yap: formed 9 July 1944 (JACAR) or reorganized May 1944 (English Wikipedia).
- 1926 school row: Japanese Wikipedia, as consulted for this site, dates the U and Ponape Japanese schools to 1926, while an earlier reading of the sources dated the Kusaie school to 1926. 『南洋群島教育史』 (1938) could settle this.
- Not found: 1925, 1930 and 1940 island-level census tables; any typhoon in 1914–45; shrine founding dates for the four island groups; a Japanese record of the Sokehs return. The Habele pages on State Shinto and the Puluwat lighthouse could not be opened, so they were not consulted for this site.
