Clean Sweep is the war memoir of Rear Admiral Roy M. Davenport,the only U S submarine skipper to win 5 Navy Crosses for his exploits aboard the submarines USS Silversides, Haddock & Trepang during which he sank 22 ships for 154,616 tons & damaged 5 ships - including a battleship - for 62,767 tons.
As Davenport was a former professional journalist I expected a cracking read to rank alongside Dick O'Kane's "Clear the Bridge" however this book seems to be nothing more than a series of Patrol Reports expanded into book form and an hour-by-hour format leads to much needless duplication. Like most skippers Davenport had his wartime score drastically reduced by JANAC & he suffered more than most being reduced to 8 ships for 50,000 tons. JANAC was subsequently discredited & Davenport's score was re-instated but he reserves his most savage criticism for Clay Blair & his tome "Silent Victory" who quotes the JANAC score whilst knowing it was discredited,
In the Afterword Davenport extensively quotes passages attributed to him - which he vehemently contradicts - by giving his version events & calling into question the veracity of Blair's book. If Blair got Davenport's career so spectacularly wrong,how accurate is the rest of the book.
