Tony Groom, a diver in the Royal Navy's bomb and mine disposal team, had just turned 23 when he was sent to the Falklands in April 1982.
He kept a diary of his experiences and contacted the BBC News website to tell us about it. Tony re-read these diaries for the first time this year and is now planning to write a book.
See below for his diary entries from May.
FRIDAY 21 MAY 1982
We entered Port San Carlos at 0415 on Sir Tristram.
As we came into port, the ship was in darkness. Shooting could be seen but not heard, up in the hills around us. Our hearts were racing.
We came in very quietly and unopposed. All through the early hours of the morning, troops, tanks and jeeps were pouring off the ships.
I was given a job as gun's crew; it was a job I had done before.
Around 2200, we heard "Hands to action stations, gun crews close up, air raid warning red imminent". This time was for real.
Five Skyhawks and three Mirage fighter jets attacked the fleet. A large mortar bomb landed between us and the Elk - it was meant for the Elk.
It was terrifying, but fantastic.

The noise was incredible: 4.5 inch guns were going off from the warships. Bofors, Seacat missiles, Blowpipes etc were coming off of us.
Our missiles could be seen going up but we saw no planes coming down. They were so fast.
They attacked three more times, in waves of four. The gun I was on got four rounds away at a Pucara jet but missed.
At the end of the day, 14 of their planes were shot down.
I had to go to the Antrim to deal with a 1000lb UXB [unexploded bomb]. It hit the deck-head, which was the helipad, and dropped down to the floor below. It took all night to lift and get over the side.
Two Army helos [helicopters] were shot down today, both crews killed.
During this, the Ardent could be seen exploding about two miles away. It sunk around 0700 - 20 died.
The survivors came on board us (Antrim) and other ships. Got no sleep.
The chopper on the flight deck was riddled with holes and a sergeant who was manning the machine gun was killed. The flight deck was covered in blood and holes from shrapnel and rockets.
The injured were in the wardroom; crying could be heard.
SATURDAY 22 MAY 1982
Just about daylight, still on Antrim.
From the bridge came "air-raid warning red imminent". We all got deep into the ship for cover.
Five minutes later, we were lying in the main passageway, anti-flash and lifejackets on. We could hear the two-inch rockets hitting the ship's superstructure.
It's bloody frightening: there were about 200 of us lying, face-down, hands over our heads, in the main passageway - praying.
Two Army helos [helicopters] were shot down today, both crews killed.
Got back to Tristram and were sent away again to HMS Argonaut. She has two UXBs, both 1000lbs. One had gone through the port side, a foot above the water line.
It did a full circuit of the boiler room and came to rest under the ladder of the engine room.

The second bomb went in the forward magazine five foot below the water line, ripped right through the ship, hit the hull off the starboard side - there is a four foot long rip in that side. It then went up, hit the roof and landed back down on top of two Seacat anti-aircraft rockets.
One of the rockets partially ignited and welded itself to the bomb. There is broken ammo all over the magazine.
The magazine flooded when the bomb went in and killed two young sailors, drowned.
The RE [Royal Engineer] did the one in the boiler room - defused.
SUNDAY 23 MAY 1982
Another clear day.
Some of the lads went over to Argonaut to measure up the holes to make patches.
They have to do the job at night due to constant action stations during the day.
We have half an hour to get all our gear off the Tristram as she is going to sea. Loading gear onto small landing craft to go to the Intrepid. Air-raid during the loading.
Got a letter from Marie - it took half an hour to read because I was under a table in the dining room sheltering from the raid.
A very bad one.
Antelope, Fearless and Yarmouth hit. Antelope got two UXBs, both above the water line. All we could see were two holes like that on Argonaut. REs left us to defuse them.
Tony Groom and colleague lifting bomb through hole cut in ship
Left Tristram, stopped at Argonaut to drop off a water pump.
Approx 1900, while alongside the Argonaut, a huge explosion took place. Everyone hit the floor because it was very close.
The UXB on the Antelope had blown up while the REs were defusing it.
There was a hole in the ship's side about 30 foot wide and four decks high. The fire took over immediately.
All landing craft and choppers went to assist. We and others got hoses into the hole but it did no good.
The ship's company were taken off after about 10 minutes, all boats told to get clear as it was very close to the Seacat and torpedo magazines.
We waited and watched for about three hours totally helpless and almost silent. Returned to the Intrepid 0400, unloaded our gear and slept on the floor - although exhausted, not much sleep was got by any.
I felt sick because of what we'd seen. I think that's when it really sank in.
MONDAY 24 MAY 1982
0800: Antelope still burning about one mile away.
The fire helped by the wind had gone from the bridge to the stern, gutting it. We were amazed it was still afloat.
Dave, Boss and Stan went to look at the bomb on Argonaut, not a popular job after last night's viewing.
Ben, myself and others went to patch a hole on the Argonaut, also not a popular job. There's not many popular jobs about anymore.
HMS Antelope on fire, after being hit the night before
While working (diving to patch up) on Argonaut, an air-raid was said to be imminent. We left the ship in the landing craft to head for the nearest beach.
Before getting there, four Mirage fighters came over the southern mountain, sheltering one Canberra bomber.
One bomb hit the Sir Geraint and one hit Sir Percival. The one we were on the previous day (Sir Tristram) was in between these two before going to sea.
Again, neither bomb exploded, both 1000lbs.
The Canberra came over our head with one Mirage. Both were hit. Rapiers, Sea Cats and all sorts of missiles were chasing the jets. It was like Star Wars, but real.
We saw the smoke appear from two fighters and the Canberra hit a hillside rather quicker than he ought.
We had just left the St Geraint 10 minutes ago.
Bullets were coming across the water from all directions. Another air-raid followed five minutes later. We had gone aground by then but we weren't too bothered about that.
The next wave came from completely the opposite direction. Five Mirages. Two didn't get even halfway across the valley; one was got by Sea Cat [missile] and one by 40/60 [anti-aircraft gun] then hundreds of marines with machine guns.
The other three came over us and the rest of the ships. We could see a rapier missile chasing a Mirage.
We were jumping up and down and screaming at this missile to go faster, and it did.
The Mirage let out black smoke and visibly slowed down. Not one of the five left the valley.
The shouting and cheering could be heard for miles as one by one they hit the water and the hills around us.
A Harrier which just made it back to deck before running out of fuel
All this took no more than a minute, as the jets are going so fast. Thirteen aircraft were shot down by the fleet and the Harriers.
One was killed on the Sir Percy, three on the Sir Geraint. If the bombs had gone off? Hundreds maybe?
Boss, Dave and Stan spent the night working on the Argonaut. The plan is that it will take four days to get it out again.
TUESDAY 25 MAY 1982
Up at 0500, Some ships thought they had heard something on the ships' bottoms (limpets?)
We split the team into three. Divers searched all but nothing was found. For the rest of the day, the raids were said to have been beaten off by Harriers.
Morbid and high tempers set in. Not had a wash for three days now
The first happy day we'd had for a while. Reports came in every time the Coventry shot down a plane.
Cheers went up accordingly.
Five planes she'd got. That's why we'd not seen any today. They'd all been attacking her about 10 miles away.
1805: Gloom and despondency set in again as we were told the Coventry was being abandoned. Twenty-two died, 20 casualties.
An hour later, the Atlantic Conveyor was hit by two Exocet. She was carrying RAF Harriers and choppers.
A chopper and a Harrier preparing for take-off
Broadsword was also hit by one of those non exploding bombs. It hit the flight deck at an angle and went out of the side.
Morbid and high tempers set in again.
Not had a wash for three days now. What's new?
(Some of this is written a day or more late.)
WEDNESDAY 26 MAY 1982
The 1600 raid came at half five today.
Three waves of four. The first two waves were said to have been chased off by the Harriers.
We were lying down under cover on Intrepid waiting for news on the third raid. We couldn't see what was going on as we were three decks down.
The frigates opened up on the other side of the valley. Thirty seconds later we were told [an Argentine plane] had just crashed in the water about a mile and a half up the sound.
The pilot had ejected. He was the only one of three.
We thought maybe they'd been attacking one of the ships further out again, but luckily nothing was heard.
As it got dark, six of the lads went over again to shift the ammo etc from around the bomb on HMS Argonaut.
It took all night.
I couldn't for the life of me figure out what day it was today, or the date, nor did anybody around me know
The patches we put on are holding well. Not much water at all is getting into magazine.
Found one of the lads' wallets who was killed.
SAS went ashore at midnight to cause havoc around Port Stanley (about 60 SAS and 30 SBS) - should pick them up in a few days. They're not trying to take Stanley, just frighten them a little.
Something really tragic happened today, we ran out of beer.
I couldn't for the life of me figure out what day it was today, or the date, nor did anybody around me know. It makes no difference what day it is or what time it is, it all just rolls on into each other.
THURSDAY 27 MAY 1982
Got to bed early last night, half 12.
Got next to no sleep.
My long-awaited wisdom tooth has started poking its head out and I have an ulcer to go with it.
Dave, Stan and Boss went over to Argonaut this morning.
Ship's company have started cutting holes in roofs and ship's side to lift the bomb up and out the side. During the cutting, sparks caught fire to something and the forward part of the ship caught fire.
The compartment with the bomb was flooded immediately (by ship's damage control party).
We stood on the upper deck of Intrepid and watched the smoke billowing out of her.
Eventually the fire was brought under control.
Rocket damage to HMS Antrim
Thank God. Dave was somewhat worried.
Lots of the ships have gone now. Canberra to South Georgia with Elk to pick up QE2's troops so it leaves us a better chance of being hit.
Intrepid was missed narrowly two days ago, I'm told.
It was while I was on the beach on the landing craft.
At 1300, went over to look at the bomb on Sir Geraint. It was in a fairly easy place to get out.
The fuse from the front had disappeared and the one in the back was smashed with all wires hanging out.
It had metal wrapped around it where it was spinning as it came through the three metal walls.
Made a sling and lifted it out into a Gemini (rubber boat) by crane.
We had sent the ship's company to HMS Intrepid during this.
The day before it was argued whether us or the other diving team should be ashore. They went... It seems nowhere is safe now
They didn't need much pushing. We took it away to deep water to sink it.
We sunk the Gemini as well. All that could be seen was thousands of flashes on the surface.
All day went by with no attacks.
I was on the flight deck with George and Wilky waiting to go to Argonaut. Two Pucaras came over the nearest shore to us, dropping 1000lb bombs.
We saw it as clear as daylight - only one went off, the one that hit the ammo dump.
We learned later that three had gone into the field hospital and not gone off.
Their intelligence must be good for them to know there was an ammo dump there. [Or] who in their right minds would bomb a hospital?
The casualties came on board the Intrepid most of the night. Four dead (very lucky), 40 injured (some from the hospital).
The day before it was argued whether us or the other diving team should be ashore. They went ashore, which was considered to be the safest place!
They were in that camp. It seems nowhere is safe now.
Some of the team left under the cover of darkness to do - yes, you've guessed it - Argonaut.
Tonight, it comes out and over the side.
My bloody tooth!
FRIDAY 28 MAY 1982
Bomb out by about 0500.
You have never seen a more relieved ship's company.
We'd never been so popular, drinks all round etc, hand shakes from skipper, jimmy [first lieutenant], commanders, signal from C-in-C [Commander in Chief] etc.
0800: started to lift the smashed up Sea Cats [surface to air missile] and 40/60 [anti-aircraft guns].
The Pucaras had been bombing troops but they were their own troops
Three of the Sea Cat's warheads had gone off when hit by the bomb; some of the shells were reduced to 3/4 and 1/2 inches thick.
All was smothered in diesel and oil, bits of war head and high explosives were everywhere. I don't think the two guys had a hope.
More drinkies from wardroom, first touch of gin for six weeks. Nice stuff.
Got told the Paras have taken Goose Green.
Intelligence about Argentinian meeting led to this attack
The Pucaras had been bombing troops but they were their own troops!
They shot down one and left the other two because they were doing a good job.
Bed about 0100.
Mouth and neck swollen because of this stupid tooth.
I don't think diesel helps.
SATURDAY 29 MAY 1982
It seems a lot longer than nine days.
0515, hands to action stations. Two jets dropped some bombs.
We don't think they knew where they went (the bombs).
It is the first time they've struck at night. Hope they don't make a habit of it.
If we're good we can have butter with our roll.
Back to bed at 0600.
Action stations a few times but planes believed to be attacking troops.
Dinner, or action snacks as they call them, has gone from roll and tomato and a piece of corned beef to just a roll.
Sometimes if we're good we can have butter with our roll.
Tooth man, tooth!
SUNDAY 30 MAY 1982
Went to sea in the middle of the night, woke up expecting to be in Bomb Alley.
Gone to do an RAS (replenishment at sea) with RFAs [Royal Fleet Auxiliaries] and join up with the Invincible and Exeter.
Nice to be away from Bomb Alley, we thought, we'll get a restful night's sleep. Well, that's what we thought anyway.
About 0100, I was half way up the vehicle ramp, on my way to the helo pad. Three rockets flew overhead.
Everyone dived under tables
They make a deafening noise. I and everyone else hit the deck, waiting for the bang, it didn't come. Over the tannoy came "we have just picked up a single sweep from a super standards radar, they are they horrors that carry Exocet.
The rockets were ours fired from the bridge; they exploded in a pattern around us and dropped millions of pieces of silver paper.
The Exocet is meant to go for them instead of us.
I have my doubts about this theory. It was a false alarm.
But managed to get us and everyone else worrying about the Exocet.
About 2145, some of the ship's company was watching Dirty Harry Crazy Larry on film.
Those bloody rockets went off again.
It worked again, everyone dived under the tables.
This time Exocet had been fired toward the three ships, when two miles away, this thing picks out its own targets.
Action stations, anti-flash, close all red openings etc.
One of us was to be hit.
You can see fright in people
After the Standard had fired its Exocet, the Exeter shot her down with sea dart.
Then the arrow opened up with her four to five guns on the missile and two or more sea darts were fired from Exeter. One of them hit the Exocet, both claim it of course.
All this was done by Radar of course. Of course, of course!
The two Skyhawkers that exoceted the Standard were chased off by Harriers.
It's weird, sat waiting to hear either a bang or something over the tannoy.
You can see fright in people.
We've decided we prefer Bomb Alley.
A diver departing for Wireless Ridge
At least we know what to expect and you can swim to the shore if need be.
Exocet frightens me more, I think.
Out here, we have sweep stakes on, that it'll be Exocet or torpedo tonight.
Bomb Alley in the morning.
What a thing to look forward to.
On a big downer all day, tooth has stopped me from talking, to everyone else's delight, I'm sure
Hacked off with it all and can see no quick end.
MONDAY 31 MAY 1982
Bank holiday, so what!
Wish I was in a traffic jam.
Wake up in Bomb Alley.
It doesn't get light until about 1200, then gets dark around 1900.
The Argies, this morning claimed the Invincible was hit and ablaze because of an attack last night.
Never take my clothes off when going to bed now, even sleep with my boots on
They couldn't have known the missile was shot down until we said it on the news today.
The quietest day yet. A couple of the old "air raid warning reds" but saw nothing.
Heard on the news they're rolling bombs out of the back of Hercules. They've been using Hercs to refuel their planes in the air, we think.
Never take my clothes off when going to bed now, even sleep with my boots on.
Can hear my feet humming at night.
