After the raid by Tu-16s, the Swedish changed their ROE once again. Every Soviet ship and airplane in the Baltic was now a target for the Swedish air force and the submarines of the navy. They were pissed off, is the only word that comes to mind. The Swedish booted the whole Soviet diplomatic mission to Sweden out of their nation. They declared the Soviet ambassador a persona non grata. Then they recall their staff and ambassador from the Soviet Union. The Soviets soon after declared the Swedish ambassador a persona non grata.
For the rest of the night and in to the next morning there was only a few small dog fights between the Swedish and Soviet Air Force. For the first time since the end of the World War 2, all passenger traffic on and over the Baltic sea came to a stop.
That chance at 0437, when the Swedish submarine HMS Nacken started its famous war patrol, when it sunk the B-103. This was the first victory for the Nacken, but by no means the last.
Mean time at the UN headquarters in New York City, the Soviet Ambassador there delivered a message to the Swedish Ambassador. To this day, we do not know what this message said, but the Swedish Ambassador, has been reported by more than one person to tell the Soviet Ambassador to go to hell with that message. But the general believe is the Soviet message, said the Swedish government would pay for all the damage cause so far to the Soviet military as well of given other measures that would help the Soviets.
At the same time this was going on, President Reagan order the air force to get ready to perform an Operation Nickel Grass operation to resupply the Swedish incase this when on for any length of time. Reagan didn't want to see the Swedish fold to Soviet pressure. Reagan also ordered the CIA to help out any way possible, short of getting the US in the middle of this pissing match.
The 28 for most part was a low in the action. Mostly it was dog fighting between the Swedish and Soviet Air Force. There was also the naval side, HMS Nacken sank a Whiskey class submarine in the early afternoon. But this low, would only last the day, on the 29 the war would chance.
