The largest Allied and Axis logistical failures

What were the largest Allied and Axis logistical failures of World War II?

The proposed examples are Axis dependence on inadequate fuel and industry and Allied failure to use supplies at Singapore, although Singapore's classification as a logistical failure is disputed.

The Axis attempted mechanized war against powers with much larger oil and industrial resources without adapting their forces sufficiently to scarcity. Singapore is proposed as the largest Allied logistical failure because supplies existed but were poorly understood and used. Norway provides another case in which avoiding defeat could have altered the war. The classification remains disputed: an objection treats Singapore's collapse primarily as a strategic failure.
