Passage: Conquered by Afonso de Albuquerque in 1510, Goa stood on an island surrounded by crocodile infested rivers that could, however, be waded across in some areas during the dry season. The closest and most important fording point to the city of Goa was the Passo Seco , defended by the fortress of Benastarim. As no more than 650 soldiers were left to defend Goa, every able-bodied man from among the casados  and 1500 Christian lascarins were mobilized. 1000 slaves were armed and divided into four squadrons; even  further, 300 clergymen and 200 retired soldiers volunteered to participate in the defence of the city. Dom Luís de Ataíde decided to distribute his forces in 19 critical points along the eastern river banks, where artillery batteries were established, garrisoned with 20 to 80 men and a contingent of lascarins, to keep the colossal army of Bijapur from crossing. Every battery was to have visual contact with the next and their garrisons were not to leave their posts unless ordered to. The deeper waters of the Mandovi and Zuari rivers, to the north and south respectively, were patrolled by four galleys, a half-galley and twenty small galleys called foists. On the opposite shore northwest of Goa, the Portuguese fortress of Reis Magos was supported by an anchored galleon. As the Viceroy had information that the Turks might join the "league", he armed a further 125 crafts of many different sizes to secure the control of the waters around Goa, although by then there weren't enough men to crew all the ships and defend the city simultaneously.
How many different groups were defending Goa? How many galleons were at Reis Magos? How many more Christian lascarins were there than soldiers in Goa? How many more clergymen were there than retired soldiers? How many more galleys than foists were patrolling the area? How many more slaves were there than clergymen? How many troops did the Christian lascarins and slaves make up combined? Of the several groups defending Goa, which had the most men? Were there fewer galleys or small galleys patrollling the Mandovi and Zuari rivers? Were there fewer soldiers or Christian lascarins guarding Goa? Were there more soldiers, or armed slaves? Where more slaves or Christian lascarins guarding the city? Which were there less of, galleys or foists? Which were there more of Christian lascarins or slaves? Which were there more of defending Goa - clergymen or retired soldiers? Which were there more of, clergymen or retired soldiers?
