Depth control will have considerable bearing on the success or failure of evasive tactics in connection with depth charge attacks. While deep submergence is a recourse available to assume the farthest position away from depth charges, it also enables the depth charge which is set for deep explosion to be effective at greater distances from the pressure hull. On the other hand, with the submarine at shallow depth and with depth charges exploding below, there is tendency to force the submarine up with possible complete broaching and exposure. Since all underwater explosive effects tend upward, if there is a choice, it is always preferable to have depth charges, mines, explosive sweeps, etc., explode above, rather than below, the submarine. A case is on record of a mine being exploded in direct contact with bow planes and the submarine still being able to return to port.

Well... It looks like I stand corrected. I'm still a student on the subject of U-Boats and I make mistakes and learn from the experience.
