Raid is looting and making it an adventure as the pirates do, mostly the angel's work were looted and taken back by Vikings to their homes.
Step-by-step explanation:
Vikings were the literal pirates who used to trade and were colonists too. The Vikings are mostly thought of to be Scandinavians but their ancestry had much more involvement. It was not until 793, that those were heard of in British history. The one who lurks in the bay is said to be a Viking.
They used to perform loot and call it a raid as the loot was not just because of theft purpose but because it was pride and honor to them to perform such an adventure. They used to loot for artistic metalwork and angel's work which could from antiques and of which they could be given honor.
