Robert Bartels joined the Reichsmarine in 1935. From 1937 to June 1940, he served as a watch officer on U-21. He went through U-boat familiarisation in July 1940 in preparation for his own command. On 24 July 1940 Bartels commissioned the new Type IID U-139. He left the boat on 20 December 1940. From there he went to the 1st U-boat Flotilla and another U-boat familiarisation, this time in order to prepare for his command of the larger Type VIIC boat, U-561 on 13 March 1941. With this vessel Bartels went out on his first war patrol on 25 May 1941, a 69-day patrol where he sank one small ship. When he left the boat on 5 September 1942 after eight patrols he had sunk or destroyed five ships for over 21,000 tons and damaged another - the last three ships fell to mines laid by U-561. Bartels went through his third U-boat familiarisation in September and October 1942 in order to prepare for the much larger Type IXD2 boats. These vessels were very long range and were later converted for transport use. Bartels commissioned the new U-197 on 10 October 1942.
The day before its loss, U-197 had met with Wolfgang Lüth's U-181 where Bartels told Lüth he intended to stay in this area and hunt the traffic Lüth had told him about. Their radio chatter had allowed the Allies to pinpoint the location, finding Bartels' boat the next day. On 20 August 1943 U-197 was attacked south of Madagascar, in position Coordinates: , by a British PBY Catalina aircraft, C of No. 259 Squadron RAF, with six depth charges and slightly damaged. As the aircraft had no more bombs, it attempted to strafe with her machine guns, but the U-boat responded with AA fire. The aircraft then circled the U-boat at a safe distance and radioed for assistance. The U-boat remained on the surface, perhaps assuming that any support was unlikely, and that the aircraft would eventually have to abandon her vigil. Unfortunately for the German submarine, another Catalina, FP 313 of 265 Squadron, arrived. U-197 promptly crash-dived, and the aircraft dropped three depth charges, two of which detonated to port of the U-boat, but the third hit her squarely, killing all 67 hands. The pilot, captain Ernest Robin, received the Distinguished Flying Cross for the sinking of the vessel.
Eitel-Friedrich Kentrat, commander of U-196, was severely criticised by the Befehlshaber der U-Boote (BdU) [U-boat headquarters] for his lack of support for U-197. Bartels of U-197 had radioed a distress signal. The correct response by any boat in the vicinity, according to orders, would have been to assist at top speed. The BdU twice ordered U-196 to aid U-197 before Kentrat responded, and by that time U-197 and the entire crew were lost.
