Question: What river in south Central America saw a battle fought on its right bank on 19 December 1810
Context: Teesta Bazaar is a small town located 4 km downstream from the town of Melli on the right bank of Teesta River in Darjeeling district of the state of West Bengal, India.  It is a road junction on Siliguri-Gangtok National Highway NH31A and the roads from Darjeeling and Kalimpong join NH31A near here.  The national highway NH31 crosses Teesta River here.  Darjeeling is on the west of the river and Kalimpong is on the east of the river.  Leaving NH31A and continuing upriver on the right bank from Siliguri on a narrower road, the smaller road leads to Darjeeling towards the west.  Continuing on NH31A on the left bank of the river after crossing the bridge, the road towards Kalimpong takes off at a junction 3 km ahead of the bridge. The Battle of Ticinus was a battle of the Second Punic War fought between the Carthaginian forces of Hannibal and the Romans under Publius Cornelius Scipio in November 218 BC.  The battle took place in the flat country of Pavia county on the right bank of the Ticino River, not far north from its confluence (from the north) with the Po River.  The battle is named from the river, not the nearby contemporaneous settlement of Ticinum (today's Pavia).  Although the precise location is not known, it is generally accepted that a settlement known today as Vigevano is mentioned in Livy's text and that Scipio's camp was to the south at Gambolo, whose coordinates are given on the map.  The conflict would have been west of there.  It was the first battle of the war against the Romans that was fought on Italian soil and the first battle of the war to employ legion-sized forces.  Its loss by the Romans, and the temporary disablement of Scipio's command, set the stage for the Roman disaster at the Battle of Trebbia in December. The Battle of Tamatave (sometimes called the Battle of Madagascar or the Action of 20 May 1811) was fought off Tamatave in Madagascar between British and French frigate squadrons during the Napoleonic Wars.  The action was the final engagement of the Mauritius campaign of 1809–1811, and it saw the destruction of the last French attempt to reinforce their garrison on Mauritius.  Although the news had not reached Europe by February 1811 when the reinforcement squadron left Brest, Mauritius had been captured in December 1810 by a British invasion fleet, the French defences hampered by the lack of the supplies and troops carried aboard the frigate squadron under the command of Commodore François Roquebert in "Renommée".  Roquebert's heavily laden ships reached Mauritius on 6 May and discovered that the island was in British hands the following day, narrowly escaping a trap laid by a squadron of British frigates ordered to hunt and destroy them. The Battle of Campichuelo was a battle fought on 19 December 1810 between revolutionary forces led by Manuel Belgrano and Royalist troops on the right bank of the Paraná River, part of the Paraguay campaign of the Argentine War of Independence.  It ended with a victory for the forces of Belgrano. Hakari River (Azerbaijani: "Həkəri" ) is the left tributary of the Araz in Azerbaijan.  The river is 128 km long and flows through Qubadli District and Zangilan District.  Several populated places are along the river, like Aganli (on the left bank), Alibayli (on the right bank), Mammadbayli (on the left bank) and Yenikend (on the right bank).  The Armenia–Azerbaijan border runs near the river. Admiral Charles Gordon, CB (c. 1781 – 3 October 1860) was an officer of the British Royal Navy during the nineteenth century.  Gordon's most notable action was the Action of 18 September 1810, when he was seriously wounded in battle and his frigate HMS "Ceylon" captured by the French frigate "Vénus".  Gordon was recaptured by Commodore Josias Rowley the following day and later took part in the capture of Île de France.  This was the second occasion on which Gordon had been captured, but he had also distinguished himself in operations against Persian Gulf pirates in the campaign of 1809 and was flag captain at the capture of Île de France in December 1810.  His later career was unremarkable, although he eventually rose to become an admiral and was made a Companion of the Order of the Bath before his death in 1860. Chashma Right Bank Irrigation Project (CRBIP) is located at Chashma in Damaan, Punjab, Pakistan. Chashma Right Bank canal off-takes from Chashma Barrage on its right bank and extends south ward up to Tounsa Barrage on Indus River. Roman Anton Boos (28 February 1733 (?)  in Bischofswang, near Roßhaupten - 19 December 1810, Munich) was a German sculptor. Annet Morio de L'Isle (3 January 1779 – 22 February 1828) became a French and Dutch brigade commander during the Napoleonic Wars.  In 1799 he joined a cavalry regiment and was posted to the Army of Italy in 1800 where he was wounded.  He became an aide-de-camp to Louis Bonaparte in 1804 and went with Louis when he became King of Holland in 1806.  He became a general of brigade in the Dutch army in 1809 and led a German brigade at the Third Siege of Gerona.  After the Kingdom of Holland was annexed by the First French Empire in 1810, Morio was demoted to colonel in the French army.  Starting in December 1810, he led the 16th Light Infantry Regiment at Cádiz, Albuera, Bornos and Tarifa.  He was promoted general of brigade and appointed Baron of the Empire in 1813.  He fought at Leipzig in 1813 and at Mainz in 1814.  His surname is one of the names inscribed under the Arc de Triomphe, on Column 21. The Paraná River (Spanish: "Río Paraná" , Portuguese: "Rio Paraná" , Guarani: "Ysyry Parana" ) is a river in south Central South America, running through Brazil, Paraguay, and Argentina for some 4880 km .  It is second in length only to the Amazon River among South American rivers.  The name Paraná is an abbreviation of the phrase "para rehe onáva", which comes from the Tupi language and means "like the sea" (that is, "as big as the sea").  It merges first with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean.
