Readying the patrol

Defying the surface fleet

Invisible and deadly

Submerged killer of the seas

Rapid predator

Counter the dreadnoughts

Merchant ships in danger

Minelayers on duty

Resolution to fulfill

The task lies ahead

Submerged, ready to attack

Sink and eliminate

Surface attack

Unrestricted mandate

Avoiding depth charges

Getting closer to obliterate

Code breaking

Danger from above

Strike the convoys

Blow them up

Resolution to fulfill

The task lies ahead

Submerged, ready to attack

Sink and eliminate

Facing acute shortage

Supplies are running out

A vicious task

Thousands of ships were sunk
