Kiska (177.545E
51.982N) is the westernmost of the Rat Islands in the Aleutian chain. It is
so isolated and inhospitable
that it had no permanent inhabitants in 1941. However, Kiska
Harbor was probably the best natural anchorage
in the western
Aleutians, roomy enough for 40 ships.

occupation and evacuation. The Japanese
landed on Kiska in the
predawn hours of 7 June 1942, during the Midway
campaign, and quickly rounded up the tiny group of weather observers that were the only
American personnel on the
island. So miserable is the weather
in the western Aleutians that it was not until 10 June that an American reconnaissance flight was able
to confirm that the island had been invaded. The Japanese built up an
impressive underground
base and improved
the harbor, but were unable to complete a usable airfield.
The island was bombarded on 7 August 1942 by a cruiser-destroyer force as a diversion
from the Guadalcanal landings.
After the bloody battle of Attu left the garrison isolated, the Japanese made the decision to abandon the base. By 25 July 1943 the Japanese had assembled an evacuation force of 3 light cruisers, an oiler, and 11 destroyers under Kawase some 400 miles south of Kiska, where the Japanese waited for foggy weather to cover their evacuation.
It was at this point that one of the most puzzling
incidents of the war took place, known afterwards as "The Battle of the
Pips." Warned by intelligence
that the Japanese were on the move, the
Americans had been patrolling west of Kiska, and on 22 July a group of PBYs picked up seven radar echoes ("pips") moving east. The
targets were tracked for six hours before the aircraft were forced to
return to base to refuel. Kinkaid ordered
a powerful force under Griffin
and Giffen, consisting of
3 battleships, 5 cruisers, and 9 destroyers, to
intercept.
On the night of 25-26 July, this force was steaming 90 miles south-southwest of Kiska in perfect weather conditions. An hour after midnight, Mississippi's SC radar detected seven radar echoes fifteen miles northeast. Four other ships confirmed the radar contacts and the fleet opened fire. Wichita could clearly see both the seven echoes and the peak of Kiska volcano 76 miles away. Twenty minutes later, the echoes were reported to have change course, and shortly thereafter the echoes began disappearing from radar. However, no visual contact was ever made and no wreckage was found.
The Navy officially concluded that the ships had been firing at spurious radar echoes from distant mountain ranges. It is not implausible that a distant target could appear to be 15 miles away; range aliasing is a problem for most radars. But the echoes were not along the bearing of any of the Aleutian volcanoes, and the bearings from different ships were slightly different, converging on the same point fifteen miles away. It seems clear that something was there.
A number of theories have been presented to explain the echoes. One possibility is that the echoes were from large flocks of Dusky Shearwaters, a species of seabird that flies over the ocean looking for plankton to feed on. The disappearance of the echoes would correspond to the birds settling on the ocean surface to feed. However, it is hard to imagine even the most complacent seabirds being undisturbed by the fall of large-caliber shells in their midst.
Surviving Japanese records show no surface forces
in the area at the time, but it is possible the echoes were from a
force of submarines travelling
on the surface at night. Recollections from surviving Japanese naval
officers suggest that such a force was in about the right area at the
time and was forced to submerge to avoid gunfire. It is even possible
that the submarines were deliberately decoying the American surface
force: As a result of the "battle", the American ships were forced to
return to base to refuel and rearm, and it was during this interval
that Kawase's evacuation force made its dash to Kiska. The force
reached the harbor on 28 July and embarked the entire garrison in less
than an hour.

occupation. Although some American commanders were suspicious
that the Japanese had already pulled out, based on reconnaissance
flights showing no ground or antiaircraft
activity, the Kiska landings took place as scheduled on 15 August 1943.
The invasion force consisted of 7 Division (now
under Corlett) and 4 Regiment, as
at Attu, but reinforced by 13 Royal Canadian
Infantry Brigade, the 5000 men of 87 Mountain
Combat Team, and the
2500
men of 1
Special
Service
Force. They found that the island was deserted, but not before 21
men were killed in friendly fire
incidents ashore and another 71 drowned when destroyer Abner
Read hit a mine in the
harbor.
