Task: Question Generation
Input (English): Passage: Having conquered Kandy, King Rajasinha I of Sitawaka turned his attention to the Portuguese stronghold at Colombo. He timed the campaign to begin shortly after the start of the monsoon season, so the Portuguese would not be able to send reinforcements by sea. The Sinhalese army appeared around Colombo on 4 June, consisting of 50,000 men, 2200 pack elephants, 40,000 oxen and 150 small calibre bronze cannon. Supporting the army were 65 light galleys which were to blockade the fortress by sea. The Portuguese captain defending Colombo was João Correia de Brito, who had 300 Portuguese soldiers assisted by 700 Lascarins, plus a civilian population of some 60,000. Foreseeing the possibility of a siege, he had stockpiled supplies of food and ammunition. The Portuguese flotilla of 6 galleys was beached due to the weather, but nevertheless Brito sent a small craft over the sea to Goa with a distress call.
Output (English): How many animals total did the Sinhalese army have?
