Guadalcanal Campaign: Strategy & Impact

• The tide of Japanese expansion was halted and reversed as the Allies went on the offensive.

Allied Offensive on New Guinea

• Territory north of Australia
• Easy to support troops due to Allied fleet proximity
• Easy to move in supplies because of proximity to mainland Australia
• The Japanese were contained there

Japanese in New Guinea

• The Japanese had originally landed on the north side of New Guinea
• A guerilla campaign contained them near Salamaua
• An invasion force was to land at Port Moresby, giving Japanese overall control
• The invasion halted due to lack of clear Japanese victory at the Battle of the Coral sea

Allied Counter-Offensive

• Australian troops, supported by a smaller force of Americans, assembled on the south side of the island
• July and August 1942, clashes broke out between Allies and newly arrived Japanese troops
• Australian forces conducted a fighting retreat, gaining valuable experience of jungle fighting
• Extended supply lines and Allied air attacks hampered the Japanese advance
• In late September, Allies began their offensive
• Over the next year, they launched successful attacks against the Japanese
• The Allies inflicted far heavier casualties than they received by:
  • Cross-country marches
• Amphibious landings
• Japanese troops were repeatedly isolated, leading to retreat or tiny enclaves
• The Japanese lost supply lines, reinforcements lost at sea, and their situation became desperate
• 13,500 Japanese soldiers held on in New Guinea until the war's end

Guadalcanal

• British possession in the Solomon Islands
• July 1942, Japanese landed and began building an airstrip
• US Marines hastily invaded to prevent a Japanese air base
• August 7, they landed and took the airfield the next day, giving them a base of operations
• The Japanese withdrew into the jungle
• Marines finished the airfield to land their own planes

Naval Warfare and Control of the Seas

• Control of the seas around Guadalcanal was vital
• The Japanese initially had the naval advantage, bombing American ground troops with planes and naval guns
• For three months, Americans/Australians couldn't risk sending ships to support the Marines
• In November, the Allies achieved a naval victory, sinking two Japanese battleships
• Allies took control of the waters, ensuring their own supplies and depriving the Japanese of theirs

Ground Warfare and Tactics

• Marines dug in around the airfield, supported by an air group with limited resources
• Americans experienced Japanese tactics for the first time:
  • Banzai charges where hundreds raced fearlessly at enemy gun lines
  • Fierce fighting with desperate charges leading to heavy casualties
  • Sometimes brutal hand-to-hand combat

Dark Aspects of Combat

• Wounded Japanese soldiers would feign death, then attack
• American soldiers began shooting or stabbing corpses to avoid attacks
• The Japanese unwillingness to accept capture or defeat changed their opponents

Conditions on Guadalcanal

• Dysentery and malaria took its toll
• Shortages of supplies and sleep, night watches, and shore bombardments weakened the men
• The Japanese faced the same problems

Japanese Withdrawal

• Japanese government weary of losses
• In February, they secretly withdrew their troops from the island, leaving it to the Americans

Other Operations

• In February 1943, Americans landed in the Russell Islands
• A campaign of air attacks in the Aleutians from August 1942, culminating in an invasion in May 1943
• US Seized control of the islands, putting them within bombing range of Japan
• Operations around New Britain led to isolation of the large Japanese force at Rabaul

Burma

• British, including imperial troops from India, tried to hold out/go on offensive against Japanese
• They weren't prepared for Japanese offensives through supposedly impassable jungle, turning the Allied flank
• Two small Allied offensives during the dry season proved ineffective; they withdrew toward the Indian border

Instability in India

• India, the British base in the region, was becoming unstable; troops committed to keeping peace
• Famine in Bengal added to already growing resentment of British rule, reducing Burma forces

New British Fighting Methods

• In jungles/hills of Burma, the British changed ways of fighting
• Guerilla warfare techniques were developed into a new military doctrine by innovators like Orde Wingate
• Chindit irregulars used long marches/air drops to penetrate behind Japanese lines, disrupting communications/supplies
• They used the jungle, avoiding places where Japanese could bring tanks/heavy artillery
• The practical effectiveness of the Chindits was limited
• Their bold campaigns unsettled the Japanese/boosted Allied morale

Local Forces Assisted

• The British used recruiting local forces to resist the Japanese
• Special operatives went behind the lines to recruit local tribes/former Burma Rifles for a future uprising
• Like in Europe, the Allies kept their enemies stretched thin by supporting resistance

Japanese Rule in the Pacific

• Japanese rule in the Pacific was particularly harsh
• Brutal punishment of dissidents and captured enemy combatants was common
• Thousands of Allied servicemen died in terrible prison conditions, along with Western civilians in camps
• An imperial regime was willing to use cruel tactics to achieve its aims
• The Japanese earned a particularly terrible reputation among their neighbors.
