About the diary: The entries here are extracted from Maximo M. Kalaw’s The Development of Philippine Politics which in turn cites “the diaries entitled Apuntes y Diario de Operaciones sobre la guerra Hispano-Filipino-Americana.” In a footnote on p. 255 of his book, Kalaw says, “These Apuntes are still in MS. form but copies of them have been made and the writer is keeping one of them.” The manuscript, in turn, is listed in the catalog of the library of Kalaw which was prepared before World War II by E. Arsenio Manuel and mentioned in his article, “Teodoro M. Kalaw’s Collection of Revolutionary Notes,” which appeared in Vol. 48, No. 3 (2000) of Philippine Studies.
