The Spain Cross was given for outstanding service during the Spanish Civil War from 1936 to 1939. It was only lend on the 6 June, 1939. On this day the Legion Condor paraded in front of Hitler in Berlin. The Spanish Cross was awarded in all classes a total of 26,117 times. The highest class, the Spanienkreuz mit Schwertern in Gold mit Brillanten was given only 29 times mostly for pilots like the later aces Galland, Mölders and Oesau. The Spanish Cross was awarded in four classes with swords and two classes without swords:

Spanienkreuz mit Schwertern in Gold mit Brillanten Spanienkreuz mit Schwertern in Gold Spanienkreuz mit Schwertern in Silber Spanienkreuz mit Schwertern in Bronze (Spanish Cross in Gold, Silver, Bronze with swords and diamonds) Spanienkreuz in Silber ohne Schwerter Spanienkreuz in Bronze ohne Schwerter (Spanish Cross in Silver and Bronze without swords)

More than 50 U-boat men wore the Spanish Cross, but most of them earned the Cross not on U-boats. So received for example Kaptlt. Gerhard Bigalk his Spanish Cross with Swords for 31 sorties on a reconnaissance aircraft. Also a lot of Crosses were awarded for duty on great ships like the Deutschland, Admiral Scheer and several torpedo boats.

A few U-boats took part on this prewar incidents during the so called operation Ursula. Only a handful of U-boat men were decorated for service on U-boats in Spanish waters. The officers from the following boats received on 6 June, 1939 the Spanish Cross in Bronze without Swords: U-25   Kptlt. Günther Frauenheim U-31   Oblt. Claus Korth U-28   Oblt. Fritz-Julius Lemp U-27   Oblt. Wolfgang Lüth U-33   Kptlt. Wilhelm Schulz U-26   Fähnr. (Ing) Erich Zürn

It had been said, that the commander of U-34 Kptlt. Harald Grosse sank on the 12th December, 1936 the Spanish Republican submarine C 3 and therefore became the only German Navy officer to receive the Spanish Cross in Gold with Swords, but I have no confirmation for either fact.
