The archive holdings of the Warsaw Sacramentines were destroyed during the war in 1944. The only item that survived was the catalogue of the collection. It is so detailed that it has been possible to get at least a general idea the material that had been lost. Recently, however, two accounts register covering the period from 1774 until 1836 have been found. They are written in French (the Sacramentines hailed originally from France). The income and expense entries put down by the sister dépositaire may, among other things, be used as a source for a reconstruction of the history of the convent school. The girls names, entered as their fees were paid, give us an idea of the geographical and social milieus from which the school recruited its punils and which in turn must have been affected by the reentry of women whose minds and attitudes were shaped by the education they received at the convent school. To the old educational template which consisted of reading, writing, catechism, simple arithmetic, music, French and embroidery new subjects were being added in quick succession. They were history, geography, literature, foreign languages, calligraphy and natural history. We can also note the reaction of the religious staff to the imposition of state control and mandatory hiring of lay teachers. The nuns endeavoured to pass the necessary examinations in order to be able to teach as many of the new subjects as possible.
