When the Belgian War of Independence began, Van Speijk was given command of a Dutch gunboat. Van Speijk despised the Belgian independence movement, and he said he would rather die "than become an infamous Brabander". On February 5, 1831, a gale blew his gunboat into the quay at the port of Antwerp. The Belgians quickly stormed his ship, demanding Van Speijk haul down the Dutch flag. Rather than surrender his ship, he fired a pistol (some versions say he threw a lighted cigar) into a barrel of gunpowder in the ship's magazine. According to legend, he shouted "Dan liever de lucht in" ( "(I'd) rather be blown up"). The number of Belgians killed is unknown, though it probably numbered in the dozens. Twenty-eight of his 31 crewmen also perished in the blast.
