Keeping control during the Rajang River confrontation

How did Clapp handle the confrontation with Indonesian patrol boats?

He kept calm while other ships fired, maneuvered deliberately with his limited weapons, and captured a patrol boat without losing control of the situation.

Clapp commanded the minesweeper HMS Puncheston with only light weapons and a bow that obstructed forward fire. When other vessels began firing in confusion, he refused to join the panic and deliberately closed the approaching Indonesian patrol boats. His crew disabled one boat with a hit to its machinery and captured it, earning Clapp a mention in dispatches. In a later encounter, Indonesian craft withdrew when RAF Hawker Hunters arrived overhead. That second incident demonstrates useful joint action, but the speakers note that Royal Navy-RAF relations in the theater were often less cooperative. Clapp treated restraint as an active command skill, controlling escalation while remaining ready to fight.
