Question: What was the date of the battle named after the state where WRIU broadcasts?

full_context: Document 1: American Revolutionary War: British attempts to disarm the Massachusetts militia at Concord in April 1775 led to open combat. Militia forces then besieged Boston, forcing a British evacuation in March 1776, and Congress appointed George Washington to command the Continental Army. Concurrently, an American attempt to invade Quebec and raise rebellion against the British failed decisively. On July 2, 1776, the Continental Congress voted for independence, issuing its declaration on July 4. Sir William Howe launched a British counter-offensive, capturing New York City and leaving American morale at a low ebb. However, victories at Trenton and Princeton restored American confidence. In 1777, the British launched an invasion from Quebec under John Burgoyne, intending to isolate the New England Colonies. Instead of assisting this effort, Howe took his army on a separate campaign against Philadelphia, and Burgoyne was decisively defeated at Saratoga in October 1777.
Document 2: Battle of Long Island: The Battle of Long Island is also known as the Battle of Brooklyn and the Battle of Brooklyn Heights. It was fought on August 27, 1776 and was the first major battle of the American Revolutionary War to take place after the United States declared its independence on July 4, 1776. It was a victory for the British Army and the beginning of a successful campaign that gave them control of the strategically important city of New York. In terms of troop deployment and fighting, it was the largest battle of the entire war.
Document 3: Battle of Setauket: The Battle of Setauket (August 22, 1777) was a failed attack during the American Revolutionary War on a fortified Loyalist outpost in Setauket, Long Island, New York, by a force of Continental Army troops from Connecticut under the command of Brigadier General Samuel Holden Parsons.
Document 4: Battle of Rhode Island: The Battle of Rhode Island (also known as the Battle of Quaker Hill and the Battle of Newport) took place on August 29, 1778. Continental Army and militia forces under the command of General John Sullivan had been besieging the British forces in Newport, Rhode Island, which is situated on Aquidneck Island, but they had finally abandoned their siege and were withdrawing to the northern part of the island. The British forces then sortied, supported by recently arrived Royal Navy ships, and they attacked the retreating Americans. The battle ended inconclusively, but the Continental forces withdrew to the mainland and left Aquidneck Island in British hands.
Document 5: Adult contemporary music: The "soft" AC format has reinvented in the late 2000s/early 2010s as a result of its declining relevance, adopting a more upmarket, middle-of-the-road approach, with a selection of "oldies" (usually from the 1960s/70s onwards), primarily rock, jazz, R&B and pop music. Newer songs are more often (but not limited to) "easy listening" fare, this amount varying depending on the age of the station's target demographic.
Document 6: CFTI-FM: On November 28, 1994, Melvin Augustine (on behalf of a not-for-profit organization) received approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to operate a new native-language radio station at Big Cove, New Brunswick on the frequency of 101.5 MHz. On February 25, 1998, the station received approval to change CFTI-FM's frequency from 101.5 MHz to 101.1 MHz and to increase the effective radiated power from 3 watts to 50 watts.
Document 7: Northern Seven Years' War: In 1762, towards the end of the war, French forces attacked St. John's, Newfoundland. If successful, the expedition would have strengthened France's hand at the negotiating table. Although they took St. John's and raided nearby settlements, the French forces were eventually defeated by British troops at the Battle of Signal Hill. This was the final battle of the war in North America, and it forced the French to surrender to Lieutenant Colonel William Amherst. The victorious British now controlled all of eastern North America.

Document 9: History of radio: On February 17, 1919, station 9XM at the University of Wisconsin in Madison broadcast human speech to the public at large. 9XM was first experimentally licensed in 1914, began regular Morse code transmissions in 1916, and its first music broadcast in 1917. Regularly scheduled broadcasts of voice and music began in January 1921. That station is still on the air today as WHA.
Document 10: WCUR: 91.7 WCUR FM "The Curve", also known as West Chester University Radio, is a college radio station that broadcasts in the Philadelphia area via a transmitter that covers a 5-mile radius around West Chester University in West Chester, Pennsylvania. WCUR offers a wide variety of music, news, sports, and specialty programming. WCUR is considered a free format station, and it does not require that DJs play within certain parameters. All undergraduate students of West Chester University are free to participate and become DJs. WCUR began as WCSC AM 64, a carrier current station only available on campus. The call sign WCUR was being used in 1974. In 1976 the on air slogan became 64CUR and a Part 15 FM transmission was added at .1 watt to serve the Sykes Student Union building and extend across the street to Killnger Hall. Efforts began at that time to seek a class A FM license, but funds were not approved. In the mid-1980s the station changed its call letters to WCUR AM 68, but it remained a carrier current station. In 1998, the station received a construction permit to build an FM station, and after installing a broadcast transmitter and antenna atop Sykes Student Union in the summer of 1999, the station signed on as WCUR 91.7 FM on September 1, 1999. Since 2001, WCUR also streams live on air from anywhere in the world from its website, www.wcur.org.
Document 11: WAJM: WAJM, assigned to 88.9 FM and licensed to Atlantic City, New Jersey, is a high school radio station owned by the Atlantic City Board of Education and is operated by the students of Atlantic City High School. Currently, WAJM broadcasts live Monday thru Friday from 7:00am to 3:30pm and during after hours, on weekends, holidays and when Atlantic City High School is closed due to inclement weather the station operates on an automated system where music, station IDs and PSA are shuffled and broadcast on-air. Starting at its inception WAJM had been broadcasting with a jazz radio format until 2009 when it flipped to a freeform radio format using the moniker 88.9 The Jam. The studios, offices and transmitter are located on the campus of Atlantic City High School on North Albany Avenue in Atlantic City. In 2009 WAJM began simulcasting its live and automated broadcasts via the Internet in both an audio only feed and audio/video feed. The station was a creation of Mr.Norman Draper. The first school year of on air broadcasting was 1996-97. That year the students interviewed "Sugar" Ray Leonard, and did a live simulcast from the grand opening of the new Atlantic City Convention Center.
Document 12: Battle of Signal Hill: The Battle of Signal Hill was fought on September 15, 1762, and was the last battle of the North American theatre of the Seven Years' War. The British under Lieutenant Colonel William Amherst forced the French to surrender St. John's, which they had seized earlier that year in a surprise attack.
Document 13: WBNQ: WBNQ first signed on the air as WJBC-FM in the late 1940s. It was the practice among the early FM stations to simply add FM to the "sister" AM call letters and simulcast programming. After the call letter change to WBNQ in the 1960s, the station aired a home-grown easy listening/beautiful music automated format recorded at the old studio site above the Castle Theater in downtown Bloomington. In August 1972 WBNQ became an oldies station using the Draper-Blore Olde Golde syndicated format, then changed to the Drake-Chenault Solid Gold format in 1974 and evolved Top 40 using Drake-Chenault's XT-40 format in late spring 1975. In the spring 1976 Arbitron, using Drake-Chenault's XT-40 format, WBNQ attained its highest ever 12+ share of 24.3%, making it one of the highest-rated FM stations in the U.S. at that time. In 1976 Denny Adkins, the operations director of WBNQ, joined Drake-Chenault as a programming consultant working with their client stations on format presentation, promotion and community involvement. Adkins rose through the ranks at D-C, becoming president in 1985.
Document 14: WRIU: When the station first signed on in 1964 (located at 91.9 on the dial at that time) WRIU's music format was mostly jazz, classical, some folk music, and easy listening. The station signal was 10 watts and coverage was generally just nearby to the Campus, sometimes reaching farther. When the station wished to expand in about 1971, installing a more powerful signal with updated facilities, the U.S. Federal Communications Commission (FCC) requirements included surveying the current and potential audience- mostly URI students- to show support for FCC approval of such expansion. A music listener survey was conducted by WRIU staff, collated, and results were published to help establish a new format based on the survey of listener preferences. This helped WRIU gain the support of URI students and the URI Student Senate, which voted to fund the purchase of equipment for expansion by about 1972. The new music format that was established in 1971 was unique in Rhode Island and continues, flexibly now inclusive of many new musical influences.
Document 15: Doug Fabrizio: Fabrizio began working for the University of Utah FM news/music station KUER in 1987, and became News Director in 1993. In 2001 he was one of the originators of the program "RadioWest" on the station. The format then, as at present, is a 55-minute interview with an invited prominent guest on a pre-announced topic. Listeners are usually able to call in with questions or comments. After a few years of growing audience acceptance and participation, the show was picked up for broadcast on Sirius XM Public Radio, where it aired for 5 years. On his RadioWest show, Fabrizio has hosted such luminaries as Madeleine Albright, Isabel Allende, the Dalai Lama and Desmond Tutu.
