Example Input: Passage: After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
 Link Information: none Question: In which country did 20 Battery Royal Artillery go to war?

Example Input: Passage: During the Morean War, monastery was in peril twice. Apparently, during the first plunder of Cetinje, after the Battle of Vrtijeljka, the forces of Süleyman Bushati did not gravely damage the monastery. Their idea was to pacify Montenegrins, and prevent them from aiding Venetian war effort. On the other hand, his army comprised a considerable amount of forcibly mobilised Christians, and he was afraid of mutiny. The popular tale has it that expeditionary force did start to rob the monastery, however, as one of the soldiers was trying to take down a cross from the top of the roof, he was struck by lightning, which was immediately perceived as Gods sign. In 1689, the Venetians were invited to take control of Cetinje. As they arrived, they quickly fortified themselves in the monastery and in the nearby former court of Crnojević. It thus served as a garrison for three years, when Cetinje was attacked again by Suleyman on 25 September 1692. Instead of fighting, Venetians entered negotiations, and reached an agreement to abandon the monastery under honorable terms. However, they mined a monastery with a time bomb, which set of in the evening hours, right after Venetians retreated and as the Ottomans were victoriously entering the monastery, killing many of them in the process. This resulted in seat of Metropolitanate being moved to Dobrska Ćelija monastery for some time. Vladika Danilo reestablished it, in 1701 or 1704, across the site of the first location, atop the remains of the court with stone from the old one, and added a tablet with the coat of arms of the Crnojević family, and a dedication to Ivan Crnojević. Before 1714, it was burnt, and then it was reconstructed yet again around 1743 by Metropolitan Sava Petrović Njegoš. It was the center of spiritual, cultural and political life of the Prince-Bishopric of Montenegro. Its importance is clearly emphasised in Prince-Bishop Vasilije's exaggerated claim, written in his "History of Montenegro", that ... before its destruction, Cetinje Monastery was among the most beautiful monasteries in Europe. The last time monastery was devastated was in 1785, when Mahmud Pasha Bushati sacked Cetinje. Ultimately defeated in the Battle of Krusi, his severed head is since then kept as a relic in the monastery. It has been built on several times, the current appearance dates to 1927. The original site of the monastery, known as Ćipur (after Greek word Κήπος - Garden) was used in 1886 by Prince Nicholas of Montenegro for his Court church. The position of the newly built church follows the lineup of the original one from inside the monastery complex. Today its ruin along with couple of pillars can be seen.
