Burned on the River

Burned on the River is a side quest in the Fallout 4 Creation Club content "Solar Cannon."

Detailed Walkthrough
Find three notes, one on a Gunner at the South Boston military checkpoint and the others in two safes near Big John's salvage. Use Sarge's Clue #3 ("lining up the cards") to unlock the final safe.

The First Clue
In a note titled, "Sarge's Clue #1" can be found on a gunner named Jack who's body can be found in a trailer at the South Boston military checkpoint. The note reads as follows: "For months I've been stashing away loot, sneaking off at night, and no one suspects a thing. ''"Not that it was hard to do. They're a clever bunch of jarheads when they need to be, but give them some R&R and their minds turn messier than a grenade in a toilet.'' "Anyways, since it's easy to get lost in the wastes, I wrote a bunch of clues to help me find it. "The first clue I've filed away at the Red Rocket, to the northwest of the outpost. "I've got a cabinet rigged to open with a few dings, the trick is the number of times you have to sound the bell. ''"But like Queen always says, you gotta press your luck. That tattoo on her face is the only key you need.'' "Just count her leaves and play the tune." Following the notes instructions and going to the nearby Red Rocket gas station, you can find a wall safe that will open if you activate the bell in the foyer four times. Similarly, you can open the safe by 'hot wiring' it if you have hacker rank 1, or an intelligence of 5 or greater.

The Second Clue
After opening the wall safe in the Red Rocket, you will be given the note titled, "Sarge's Clue #2". It reads as follows: "For the next clue, I hid the safe east of here, inside a house that's painted red. ''"Of course, once I get there, I'll need a code to open it. Something that's easy to remember. And seeing as you're a godly man Sarge, I think I'll have you look to the south for a sign.'' "When you see it, just count the rockets pinned in the alley, then the craters holed in the moon, and then finally, the stars underneath." Heading to a small house not to far to the east of the Red Rocket and going behind it you will find a red dog house, and inside it is a floor safe. The code is 5-3-6, which corresponds to the bowling sign on the road.

The Third Clue
After popping open the second safe you will receive Sarge's third and final clue, "Sarge's Clue #3". It reads as follows: "I put the main stash in another safe north of here, in one of the buses tucked below the freeway overpass. ''"It's taken me a long time to get everything on my list, but it's been worth it. As far as I know, Ace, Deuce, Jack, and Queen have no idea what I got hidden away.'' "There's guns, loot, dirty magazines, and one special little blast toy I picked up at Poseidon. It's literally lightning in a gun. ''"And the code for the safe? It's as simple as lining up the cards."'' Once you find the safe inside a bus inside a nearby underpass, the code is 1-2-11-12, corresponding to the playing card values associated with the names of Sarge's gunner crew, in the order he listed there names in his third note.

Once the safe is unlocked the quest will immediately complete. Inside the safe is the "Exterminator's Solar Cannon Rifle" as well as Sarge's note and some other loot.
