Input: Question: How many people died in the battle in which Mends was seriously wounded after being struck in the head by a wooden splinter? Passage:Recovering from his wounds, Mends joined HMS Conqueror and fought at the Battle of Dominica, where he was again seriously wounded after being struck in the head by a wooden splinter. Mends remained in service at the end of the war and joined HMS Grampus in 1786, under Commodore Edward Thompson off the African coast. In 1789 he was promoted to lieutenant and spent time on the brig HMS Childers in the English Channel. At the outbreak of the French Revolutionary Wars in 1793, Mends was serving on the ship of the line HMS Colossus in the Mediterranean and was present at the Siege of Toulon. In 1795, Colossus joined the Channel Fleet and fought at the Battle of Groix, at which Mends was caught in a large explosion that left him very badly burned.
