Likely causes
Overwatering
Most likelyHow to tell: The base of the stem feels soft or mushy, and the leaves may turn yellow or wilt despite wet soil.
What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, remove the plant and trim away any black, slimy roots before repotting in fresh, well draining cactus mix.
Poor Drainage
PossibleHow to tell: The soil stays damp for more than a few days after watering, and the pot lacks holes.
What to do: Repot the plant into a container with large drainage holes. Use a gritty soil mix designed for succulents to ensure water flows through quickly.

When to worry
If the stem base is soft and smells bad, the plant is likely beyond saving. It is normal for the plant to lose a few lower leaves as it grows, but the stem should always remain firm.
Stopping it coming back
Only water your Spanish dagger every 14 to 21 days, and always ensure the soil is bone dry before adding more water.
