Forgotten history. The Aleutian Islands Campaign

I've been trying to bone up on my military history and instead of focusing on the "well reported" aspects of World War Two, I've been trying to read about some of the untold stories.

Amphibious assaults are of great interest so when I came across the Aleutian Island Campaign I was beyond hooked.  I was curious beyond belief.

Wikipedia has this passage on the battle for Kiska Island...

On 15 August 1943, an invasion force of 34,426 Allied troops landed on Kiska. Castner's Cutthroats were part of the force, but the invasion consisted mainly of units from the U.S. 7th Infantry Division. The force also included about 5,300 Canadians, mostly from the 13th Canadian Infantry Brigade of the 6th Canadian Infantry Division, but included the Canadian component of the 1st Special Service Force, also known as the "Devil′s Brigade".
The invaders landed to find the island abandoned. Under the cover of fog, the Japanese had successfully removed their troops on 28 July. The Army Air Force had bombed abandoned positions for almost three weeks without suspecting the Japanese were no longer there. The day before the withdrawal, the U.S. Navy fought an inconclusive and possibly meaningless Battle of the Pips 80 mi (70 nmi; 130 km) to the west.
The Japanese may have been gone, but Allied casualties on Kiska nevertheless numbered 313. All were the result of friendly fire, booby traps, disease, or frostbite. As with Attu, Kiska offered an extremely hostile environment.

Cracked magazine has a different take on it

When a Japanese task force of 500 marines swiftly invaded the U.S. occupied island of Kiska, the Americans decided to take it back with 35,000 men, having done the math and determined that bringing 70 times more troops than the enemy is the precise amount to say "fuck off."
On August 17, 1943, The U.S. Army stormed the beach of Kiska with a force of 95 ships, 168 aircraft and thousands of Captain Americas. They bombed the beaches with planes, destroyed the garrisons with heavy artillery and then the soldiers charged in, shooting everything that somehow still stood.
The allies took the island and suffered 122 casualties.
When the dust settled and the Americans stopped to reload, pat themselves on the back, count the bodies and have the compulsory talk about their girls waiting for them back home, they suddenly realized that they couldn't find any enemy corpses. Either that Japanese task force was comprised entirely of Predators or they had been bamboozled.
 Who Fucked Up?
The U.S. intelligence officers win the prize. After sending a plane and taking photos over Kiska, it looked a whole lot like it had been abandoned. And it had been--the Japanese had left the island two weeks before. Still, the decision was made to send in the troops and bring that nothing to justice rather than delaying the operation and checking to see that the enemy were actually fucking there. Good job, gentlemen.
It all could have been an amusing mistake, but only if you forget about the 122 dead. How do you lose over a hundred men in a battle with no enemy? Well, the losses included 24 from friendly fire, a stray mine destroying a ship and 47 men vanishing in the dense jungle. Though that last one actually lends credence to the Predator theory...

Either way you look at it whether serious or with a bit of humor this is a part of forgotten history that isn't taught or much talked about.  This campaign deserves more study.  I can't wait.
