The fleet of the Grand Duke of Tuscany was involved in several actions off the North African coast in the early 17th century. The Order of St Stephen was dedicated to fighting the Ottomans and pirates in the Mediterranean. Both the Ducal fleet and that of the Order sometimes formed parts of larger fleets in alliance with Spain, the Papacy and the Knights of Malta. Several of the captives listed in the document were from 'Bona' (Bone or Annaba, now in Algeria). Annaba was a seat of the Barbary pirates, and in 1607 was attacked by the Order of St Stephen who carried off 1500 captives. One of the captives appears to have been taken at Bona ('Abdela di Mansur di Bona ... preso a Bona'). Sometimes the name of the ship that took the captives is recorded, such as 'Giafer di Abdela d'Aleppo ... preso col' Galeon' Livorno'. Often two or more individuals were taken from the same ship, as for example six persons taken from 'un' Caramussale' [caramoussal obsolete: a Turkish and Moorish ship of burden, noted in the 17th cent. - OED]. Many were taken 'alla Ja'', one 'sopra la Ja'', and one 'vicino della Ja'' (near la Ja'), in 1608. Since one captive was from la Ja', this presumably refers to a place, probably in North Africa. Three brothers (Hadar', Aidar' and Ali di Faraatt') were captured there. A marginal note next to three individuals also captured there records 'questi tre si vogliano tagliare' (literally, 'these three wish to cut).Two entries mention 'Cavaliere Guadagni' as the captor at la Ja. The Guadagnis were a Florentine family, and according to an online history of the Guadagni family (at guadagnifamily.com, accessed 09/12/2021) Guglielmo Guadagni was commander of the Grand Duke of Tuscany's galleons, and led an attack on the fortress of Laja in 1608. This history also records that Guadagni was promoted to 'General of the Galleys of the Grand Duke of Tuscany' in 1607 as a reward for his successful expedition against Bona.
