Why Alhucemas did not become an Allied amphibious textbook

Why did the Alhucemas landing not strongly shape later Allied amphibious operations?

The explanation centers on missing observers and accounts, which left planners without enough information to study another country's landings.

The answer doubts that Alhucemas substantially informed Torch, Husky, Avalanche, or Overlord. Its explanation is the difficulty of learning from another country's operations when observers were not sent and accounts were unavailable. The Development of British Amphibious Operations 1882-1914 is used to introduce that wider problem. A later operation can resemble an earlier one without its planners having had the material needed to study the earlier experience.
