In Command
World War II rages as the new commander of HM corvette Briar, Donald Cameron, proceeds south to the Falkland Islands. His mission: blow up a channel north of Cape Horn to block the Japanese fleet's passage to the South Atlantic
But U-boats dog their journey west, and in the Falklands Japanese bombers attack from snow-filled skies. Then, after two enemy cruisers escape the Briar's trap, Cameron has a deadly choice: slip away and hide until the Japanese leave or stay and fight—one corvette against powerful, heavily gunned cruisers.
The odds are against him, but running away is not Cameron's style ...
