The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807.

Input: Consider Input: Question: Of the two teams Gallagher was loaned to in 1989, which had more wins that year? Passage:In August 1982 he joined Bruce Rioch's Torquay United on non-contract terms following his return to the UK. He was rewarded with a one-year contract, scoring nine times in 42 league games as well as the winning goal in the FA Cup tie at home to Oxford United that saw the Gulls through to the Fourth Round for only the fourth time in their history. Despite a successful season, he left at the end of it, returning to Wisbech Town debuting in the 1–0 Eastern Counties League victory at Tiptree United on 20 August 1983. He moved on to join Irish side Drogheda United, helping them defeat Athlone Town 3–1 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup. Gallagher returned to Wisbech Town for the 1984–85 season before rejoining another of his former clubs, Peterborough United, in August 1985. His second spell proved his strongest in league football, as he netted 24 goals in 82 league games, earning a move to Wolverhampton Wanderers in June 1987. He found opportunities limited at Molineux due to the prolific partnership of Steve Bull and Andy Mutch, but did play at Wembley in their victory in the Sherpa Van Trophy in May 1988. He was loaned to both Wisbech Town and Kettering Town during the following season before being released in September 1989, and joining Conference side Boston United.
