Bomber Command's low-level canal mining

What mines did Bomber Command place in German canals, and how were they delivered?

Magnetic and other mines were laid by small low-flying elements using major bombing raids as cover.

Bomber Command used magnetic and other mines against German inland waterways. Large raids drew fighters and attention toward cities while a few aircraft approached canals at low altitude beneath radar coverage and released their mines quietly. The operation paired strategic deception with maritime and logistical interdiction far from the open sea.
