California and the Second World War II
Japan Scuttled 1941 Raid on San Diego Bay
Submarines Were In Place to Deliver 'Unhappy Christmas' Message to United States

Bart Roggensack was aboard the USS Medusa, a Navy repair ship, in Pearl Harbor and his wife Elna was living with her parents and infant son in East San Diego.
 
As Bart witnessed the surprise Japanese attack that early Sunday morning, Elna heard the news on the radio.
 
Little did they or the rest of America know, then or now, that the Japanese intended to strike a blow close to home two weeks later, in a Christmas raid that targeted San Diego and other West Coast ports.
 
It was an attack that came within hours of happening, and one which could have set back the U.S. response beyond the havoc caused at Pearl Harbor.
 
According to accounts published after the war, the Japanese submarine command was planning a Christmas Eve raid on San Diego and other significant ports. Eight subs were under orders to continue east from Pearl Harbor. They halted at locations 20 miles or so off the West Coast.
 
The assignment to shell San Diego on December 24 was given to the Japanese Imperial Navy's submarine I-10.
 
The Japanese Sixth Fleet's Vice Admiral Mitsumi Shimizu, whose flagship was the submarine, HIJMS I-10, wanted to accompany the shelling with a radio greeting in English to wish President Franklin D. Roosevelt an "unhappy Christmas" but no one was available onboard to make a proper translation. Shimizu requested help for the message from Tokyo.
 
When admirals in Tokyo got wind of the plan, they spiked it and the subs headed for home waters.
 
There have been two explanations as to why the attack was called off.
 
First, after weeks at sea the subs were running low on fuel and facing increasing anti-submarine activity. Second, some officials thought it would be inappropriate to "mock" the Christian holy day."

The Tribune-Sun published an extra edition to report on the Japanese attack against the Pacific Fleet at Pearl Harbor.

Wrote John Deane Potter in "Admiral of the Pacific: The Life of Yamamoto," the mastermind of the Pearl Harbor attack, "Although they felt the stuffy old admirals could not see a joke, the submarine commanders reluctantly dropped the idea. Only one submarine disobeyed. She shelled San Diego on Christmas Eve, setting some fuel tanks on fire."
 
No other wartime accounts or subsequent histories mention such a shelling and there were no reports in the newspapers of the time of any suspicious fires.
 
Bruce Castleman, a retired Navy officer and history professor at San Diego State University, called the Potter account unreliable and guessed the British author, whose book was published in 1965, might have confused the story with a submarine shelling near Santa Barbara in February 1942.
 
Still, war planners in Japan before the outbreak of hostilities against the United States had developed various scenarios for raids, if not an invasion, targeting the West Coast.
 
A 1940 book, "How Japan Plans to Win," translated into English and published in the United States in 1942, did not receive much attention at the time.
 
But its author, Kinoaki Matsuo, spoke of a strategy that would include uprisings against the United States in Mexico, Japanese seizure or destruction of the Panama Canal, the defeat of the U.S. fleet and occupation of the Hawaiian Islands.
 
"If, in the meantime, the Japanese fleet haunts the Pacific Coast and bombards or threatens the United States merchant marine, the United States will be dealt a heavy blow," Matsuo wrote.
 
In his book, Matsuo also provided a geography lesson on the West Coast, including this passage about San Diego: "There is also the famous city of San Diego, the southernmost naval harbor of California, 126 miles from Los Angeles; this harbor as a naval base has excellent accommodations."
 
Although the Japanese navy received a blow in the Battle of Midway in June 1942 from which it never recovered, plans continued throughout the war to harass the U.S. mainland.
 
Late in 1944, the Japanese launched about 9,000 balloon bombs. Some of the weapons floated across the Pacific and landed in the Northwest, setting off a few minor forest fires. On May 5, 1945, six picnickers were killed in Oregon when a balloon bomb they dragged from the woods exploded.
 
In the summer of 1945, a more bizarre plot was developed by the Japanese navy. Called "Cherry Blossoms at Night," the plan was for kamikaze planes to drop plague-infected fleas on San Diego on September 22.

This operation only came to light in a 1995 newspaper article based on interviews with those familiar with Japan's germ warfare effort.
 
The end of the war in August 1945, after two atomic bombs had leveled Hiroshima and Nagasaki, put an end to the plan.
 
The story of the aborted West Coast raid, and other attempts to bring the Pacific war to the U.S. mainland, provide the fodder for countless what-if debates among military strategists and history buffs.
 
But for the dwindling numbers of Pearl Harbor survivors and their families, like the Roggensacks, it's the memories of the actual events – where they were and what they did – that resonate 63 years later. They lived through an experience whose intensity others can only imagine.
 
"You just never forget something like that," said Elna, 85. "It's always with you. It's in the back of your mind, but some little thing will trigger something and you'll recall the things you remember that happened."
 
The couple, now living in the Fletcher Hills area of El Cajon, have given their World War II photos and memorabilia to their son Bart Jr. But they don't need snapshots, clippings and letters to recall the events of that Sunday morning – just as a younger generation of Americans will always remember the terrorist attacks of Tuesday, September 11, 2001.
 
Elna received news of the Japanese attack as she was sitting in a rocking chair with her 4-month-old son at her parents' Central Avenue home. Her father came in and, without a word, switched on the radio about 11 a.m. that Sunday.
 
"Pretty soon . . . it dawned on me that they were talking about Pearl Harbor," she said. "Whoa, I just couldn't believe it. We just didn't know what to do or think."

Unable to reach her husband, she took her mind off the news by accompanying her brother and his wife on a short drive to the then-barren flats of Kearny Mesa.
 
"We just walked around out there and talked and prayed," she said. "Then we went back home and all we could do was just wait."
 
Three days later, a three-word, censored Western Union cablegram arrived from Bart. It said, "I am safe." He didn't see his wife and son for 22 months.
 
Bart , now 89, recalled the Pearl Harbor attack, which began minutes before 8 a.m. Hawaii time.
 
"I heard gunfire when I was down on the second deck," he recalled. "I saw the planes and was looking right at two torpedo planes with a big red ball on the fuselage and knew we were in trouble."
 
He escaped injury but he saw the destruction all around and learned later that some of his best friends had been killed.
 
Word of the attack flashed from Hawaii to the Navy's radio towers at Chollas Heights in San Diego and then to the nation's capital. Within three hours, the news had become public.
 
Soldiers and sailors returned to their bases. Blackouts began the next night. An anti-submarine net was dropped at the entrance to San Diego Bay.
 
By midweek, the Navy had taken over much of Balboa Park with plans to turn its museum buildings into wards for the naval hospital, the receiving point for many of the Pearl Harbor wounded.
 
On December 8, 1941, the front page of The San Diego Union included this headline: "Coast on Alert for Sneak Blow." A story described a city "tense – listening – greedy for more news, exact news, news that was revolting, yet news that you had to listen to."
 
Ramona's Chamber of Commerce discussed how to accommodate evacuees fleeing San Diego if an attack ensued.
 
In San Diego, the shock from the outbreak of the war gradually faded as the United States slowly took the offensive. Still, Elna Roggensack said it took at least a year before she felt secure. By then, San Diego had settled into an era of rationing, censorship and victory gardens.
 
Elsewhere, the mood was different. Elna visited her parents in Iowa in 1942 and said she was shocked at what she found to be a lack of concern.
 
"You just didn't feel like there was a war," she said. "Being in San Diego where the ships were coming and going and the military was here, you knew there was a war going on. Back there, they were quite distant."
 
Her husband did not see her until 1943 – and it took some time to convince son Bart Jr., then 2 years old, that he had a father.
 
Bart Roggensack, who had enlisted in 1936, stayed in the Navy until 1958, then took a civilian job overseeing ship repairs and retired in 1972.
 
As the outgoing president of the 155-member Pearl Harbor Survivors Association local chapter, the largest in the United States, Bart Roggensack will lead a service at the Veterans Memorial Center in Balboa Park at 9 a.m. today and relinquish his post tomorrow.
 
Since he'll turn 90 in March, he said it's time to slow down.
 
But he'll continue one ritual.
 
On the third Sunday every month, he joins other Pearl Harbor survivors to read the names of service personnel who have died in Iraq.
 
"When you hear those names, 18, 19 years old, it really gets to you," he said. "You just shed a tear, a tear rolls down your cheek. You think of those kids."
 
Just as he thinks of the kids he knew whose lives were cut short 63 years ago in a war that touched everyone.
