Input: Consider Input: Question: What country is the Bristol Channel located in? Passage:Because of the natural layout of the harbour, Ilfracombe became a significant safe port (registered port of refuge) on the Bristol Channel. It also had trade routes between Kinsale and Tenby, which made the port stronger. In 1208 it was listed as having provided King John with ships and men to invade Ireland; in 1247 it supplied a ship to the fleet that was sent to conquer the Western Isles of Scotland; 6 ships, with 79 men were sent to support the siege of Calais. Ilfracombe was the last disembarkation point for two large forces sent to subdue the Irish. The building which sits on Lantern Hill by the harbour, known as St Nicholas's Chapel (built 1361) is reputed to be the oldest working lighthouse in the UK; a light/beacon has been there for over 650 years. The town was also home to the Bowen family. James Bowen was master of HMS Queen Charlotte, the flagship of Richard, Earl Howe at the 1794 "Glorious First of June" battle. James Bowen was commissioned by Howe for his leadership in the battle, he rose through the levels - commander of the Argot, the Dreadnought, and in Georgian England titled "defender of Madeira", led the fleet which rescued the British army at Corunna in the Peninsula war, and retired as a Rear Admiral, Commissioner of the Royal Navy. Captain Richard Bowen (1761–1797) James Bowen's younger brother, a British naval commander on the ship HMS Terpsichore, served under Lord Nelson, and was killed at the battle of Santa Cruz de Tenerife. John Bowen (1780–1827), son of James Bowen, a naval officer and colonial administrator founded the first settlement of Tasmania at Risdon Cove in 1803 - the settlement which later became known as Hobart. Lieutenant A E Down, was initially posted to Ilfracombe to lead a protection ship for the customs and excise, he married a local girl, rose through the levels to retire as vice Admiral, his son joined the navy aged 14 (his first navy kit is on display at National Maritime Museum Greenwich). In 1802 James Meek married Down's daughter and settled in the town, James Meek was appointed the Comptroller of Victuals to the Royal Navy in 1832, he was knighted, and died in Ilfracombe 1852.

Input: Consider Input: Question: Did the Doncaster Rovers lose more games than Nottingham Forest the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.
