Input: Consider Input: Passage: On September 30, 1581, Nobunaga launched his own invasion of Iga on a much larger scale. The immediate trigger for this second invasion was a visit by two residents of Iga the month before to Nobunaga's stronghold in Azuchi during which the men offered to serve as guides for an invasion of the province. Nobunaga agreed and rewarded the men. By this time Oda was at the height of his power. He controlled most of central Japan, including all of the territories that bordered Iga. He was therefore able to assemble a large army which attacked the province from all directions: 1. 10,000 men under the command of Nobukatsu and Tsuda Nobusumi entering from Ise to the southeast.2. 12,000 men under Niwa Nagahide and Takigawa Kazumasu entering from Tsuge to the northeast.3. 7,000 men under Gamo Ujisato and Wakisaka Yasuharu entering from Tamataki to the north.4. 3,700 men under Tsutsui Junkei entering from Kasama to the southwest.5. 7,000 men under Asano Nagamasa entering from Hase to the southwest.6. 2,300 men under Hori Hidemasa entering from Tarao to the northwest. Against this large army of 42,000 men, the Iga defenders only totaled 10,000 at most, and these were spread throughout the province. The Oda forces advanced, torching castles, shrines, and temples, and meeting relatively little resistance. The most significant military actions were the siege of Hijiyama Castle, which had become the rallying point for the northern Iga forces, and the siege of Kashiwara Castle in the south. With the surrender of the forces in Kashiwara Castle on October 8, organized Iga resistance came to an end. Nobunaga himself toured the conquered province in early November, and then withdrew his troops, placing control in Nobukatsu's hands.
Question: How many different forces were involved on the attacking end of the second invasion?
Answer type: Number

Input: Consider Input: Passage: Brian's body was brought to Swords, north of Dublin. There it was met by the coarb of Patrick, the traditional head of the church in Ireland, who brought the body back with him to Armagh, where it was interred after twelve days of mourning. Along with Brian were the body of Murchad and the heads of Conaing, Brian's nephew, and Mothla, King of the Deisi Muman. Mael Sechnaill was restored as High King of Ireland, and remained secure in his position until his death in 1022. Though the Annals imply that life was not much changed after the death of Brian Boru, it created a succession crisis, as Brian's son and heir Murchad had died as well. Brian had two remaining sons who could challenge for the kingship: Donnchad mac Briain, his son with Gormflaith and Tadc mac Briain, his son with Echrad. According to the annals, Donnchad rallied the forces of the Dal gCais at Clontarf and lead them home to Cenn Corad. Within weeks the Dal gCais, under the new leadership of Donnchad, were battling their old masters the Eoganacht Raithlind. Tadc initially joined his brother against the Eoganacht, but would eventually be killed in 1023 at the order of Donnchad. Sigtrygg remained King of Dublin until 1036, and was apparently secure enough to go on pilgrimage to Rome in 1028. However, after Clontarf, Dublin had been reduced to a lesser power. In 1052, Diarmait mac Mael na mBo, King of Leinster, captured Dublin and Fine Gall, for the first time asserting Irish overlordship over the Norse of Ireland.
Question: How many sons did Brian have?
Answer type: Number
Output: 3.
