U-boat sinks Kong Gustav and heavily damages Viktor

The attack that sank Kong Gustav and crippled Viktor turned a distant warning into an immediate rescue and defense problem for Krause. Two white rockets astern signaled that a ship had probably been torpedoed; a message from Cadena confirmed that Viktor had been hit. Krause wheeled Keeling back at flank speed, then learned that Kong Gustav had gone down in less than five minutes and that Viktor had lost power, suffered flooding, and lost thirty men. The episode is at once a sudden reversal in the convoy’s security and a test of how much protection a damaged escort could still receive.

Readiness and the warning

Keeling was already operating under prolonged strain. The ship remained in Condition Two, with battle stations largely manned and watertight integrity maintained, but Krause regarded that state as costly to the crew and the vessel. Calling general quarters unnecessarily would bring every man to his post, interrupt sleep and meals, and leave routine maintenance undone. Battle stations could not be sustained for long; conserving that reserve mattered particularly when the crew had already been alert for danger.

Krause had therefore told the ship that there would be no routine general quarters before dawn: if the alarm sounded, it would be for a real emergency, and the watch below could have its full four hours unless circumstances changed. Keeling’s additional weapons and equipment had crowded its living spaces, while the shortage of trained ratings prevented the ship from supplying three watches in Condition Two. Krause had divided the company into four sections and instituted watch-and-watch, seeking to avoid adding an unnecessary burden to men whose readiness was already being taxed. That decision did not remove the strain; it preserved some capacity to respond when an actual threat appeared.

The ship’s defenses depended on sustained attention from people as well as equipment. Seven lookouts each swept a designated sector, pausing to wipe spray from their binocular lenses. A U-boat might reveal only a foot or two of periscope for less than half a minute, so a brief glimpse could decide the convoy’s fate. Below, sonar operator Tom Ellis had trained at the Key West Sound School but had never since heard an echo from a submarine. The narrative stresses the gap between classroom preparation and the instantaneous recognition needed in combat: an error of ten yards rather than twenty in a depth-charge attack could separate likely success from failure. These vulnerabilities frame the rockets not as an abstract alarm, but as a crisis met by a tired ship whose protection depended on fallible human vigilance.

Krause turns back

The after lookout’s report of two white rockets astern interrupted Krause’s nearly relaxed attention to the evening. He understood that the rockets meant a torpedoing unless the alarm proved false. Viktor was near the reported trouble, but roughly ten miles away or possibly farther, and Krause could not tell whether she was able to answer him or simply too occupied to do so. The Commodore’s signal lamp was directed at Keeling; the message arrived by signal pad: Cadena reported that Viktor had been hit.

The confirmation ended Krause’s indecision. He ordered a turn from course 093 to 273 and told his officer that he was going back to Viktor, somewhere astern of the convoy. He then ordered all engines ahead at flank speed. The move committed Keeling to leaving its place with the convoy to assist a stricken escort, while the limited fuel of the corvettes ruled them out as substitutes for that response. Krause’s choice was not made with full knowledge of Viktor’s condition; the report that she had been hit supplied the decisive fact, while the extent of the damage remained uncertain.

When Viktor finally answered over the T.B.S., the familiar English voice brought Krause a moment of hope, but the report was grave. The engine room had been hit and flooded; all power was lost. Viktor had rigged a jury-battery circuit to restore the radio-telephone, and Cadena was standing by to tow her. The bulkheads were holding reasonably well and being shored up, though leaks in other compartments also needed attention. Viktor could use hand steering and remain partly under control, but she was five degrees down by the stern and listed five degrees to starboard. Keeling had reached the ships and could see their dark shapes off its starboard beam.

The losses and the tow

Viktor’s officer relayed the captain’s report that Kong Gustav had been struck just before Viktor. He believed Kong Gustav had been hit by three torpedoes at short intervals, probably a spread fired from close range. The account separates what was known from what was inferred: the three fish and their timing came through the report, while the close-range spread was the captain’s judgment. Kong Gustav sank in less than five minutes. Cadena rescued her captain and some of her crew; Viktor’s crew began recovering its own survivors while their ship was sinking.

Viktor’s losses were severe. Cadena took a hundred of her ratings aboard, while thirty men had died in the engine room. The brief, restrained exchange over the radio leaves those numbers starkly visible amid the practical reports about power, leaks, steering, and towing. The ship could still be controlled to a limited degree, but her ability to fight had been sharply reduced. The immediate task had become keeping her afloat and shielding her from any further attack.

The report also disclosed how little warning the escorts had received. Viktor’s officer said that ASDIC had not heard the torpedoes being fired because there had been considerable interference. The attack was therefore not preceded by a sonar warning that could have enabled the escorts to prevent it. Cadena’s presence made rescue and towing possible, but it could not undo the loss of Kong Gustav or restore Viktor’s power. As the towing hawser went out, Viktor’s officer passed on the captain’s goodbye in case he did not see Krause again. Krause asked him to say that he looked forward to seeing the captain in Londonderry, offering a specific hope of reunion against the possibility of another loss.

Keeling’s protective circuit

Krause did not treat the tow as the end of the emergency. In the darkness Keeling circled Cadena and Viktor, with sonar searching underwater and radar scanning the surface. The damaged ships needed protection precisely when they were least able to defend themselves, and the possibility of a second U-boat attack remained. Krause calculated that a circle one mile in diameter took Keeling about twenty minutes to complete. A U-boat two miles away, outside sonar range, could cover that distance at six knots in the same time and launch a torpedo spread from half a mile. His calculation gives the protective maneuver its limits: Keeling was covering the ships as effectively as possible, but the geometry still allowed an attacker an opportunity.

The sequence thus ends not with the danger resolved but with Keeling committed to guarding two vulnerable ships while the convoy’s losses are still unfolding. Cadena’s rescue work, Viktor’s improvised radio circuit and partial hand steering, and Keeling’s circling patrol form a chain of practical responses to damage that cannot be reversed. The attack’s defining contrast is between the convoy’s organized readiness and the suddenness of the torpedoes: procedure can conserve strength, transmit reports, rescue survivors, and protect a tow, but it cannot guarantee warning or prevent death.
