Sometimes, if the water was shallow enough. WWII submarines could only dive to depths of 300-500 feet before being crushed like a drink can by the water pressure, so out in mid ocean they could not do this (and still cannot today). But in coastal waters they could, to avoid surface ships trying to find and sink them, or to lay up during the daylight hours. Sometimes, if the bottom was muddy, they could get stuck, and had a hard time freeing themselves to surface. They'd blow all the water out of the ballast tanks, and sometimes all the crew had to run back and forth, from the front of the boat to the rear, trying to rock the ship enough to break free. If they got loose they'd pop up like a cork after that.
