"The Spaniard" was the moniker of one of Captain Samuel Pike's pirates. He and another pirate found Polly Wright at the TARDIS, and took her with them to the churchyard tunnel.
They encountered Ben Jackson, who knocked out the other pirate. The Spaniard and Ben fought, but before the Spaniard could kill Ben, the Spaniard was shot and killed by revenue officer Josiah Blake. (TV: The Smugglers)
