1943: ACORN 8 arrived at Noumea. Later moved to Guadalcanal, Munda and Russells for restaging and then on to Biak. (Used during World War II, an ACORN was a tailored unit designed to carry out the rapid construction and subsequent operation of a landplane and seaplane advance base. Each ACORN had a construction battalion attached to it, as well as trained personnel to operate the control tower, field lighting, aerological unit, transportation, medical, berthing and messing facilities. A construction battalion maintenance unit (CBMU) also accompanied each ACORN to maintain the base after initial construction was completed and the construction battalion had been withdrawn. During the war, ACORNs were sent to such places as Guadalcanal, Espiritu Santo, Green Island, Rendova, Treasury Island and Majuro.)
1944: The versatile match of Seabee and bulldozer is an image which will never be forgotten by citizens of Falmouth, England. When a German air strike exploded a fuel dump and sent a river of flaming gasoline flowing downhill toward the town, Seabee Philip Bishop, NMCB 81, quickly bulldozed a dam which stopped the channel of fire and saved the community from destruction. The bulldozer-fireman received the British Empire Medal (Military) and the enduring gratitude of an English seaport town.

After recovering from their astonishment they walked over and looked into the chasm. About 15 feet down was the vanished dozer with Wiebe still at the controls with a surprised look on his face. Demolition crews blasted a ramp and the cat was driven out and back to work by Wiebe, who received only minor lacerations from his experience.
