Even from the grainy black and white footage of American soldiers wading towards shore while under fire, you can see and sense the fear, resignation and determination in that moment.

The Battle of Midway in World War II may have been won, but on August 7, 1942, the Solomon Islands campaign was just beginning.

By the end, nearly 40,000 men lost their lives here, 31,000 Japanese and 7,100 Allies.

In 2013, I travelled with a large group of New Zealand war veterans to New Caledonia, marking the war in the Pacific.

There is a New Zealand cemetery at Bourail where Kiwis who died in the Pacific are buried. It was humbling to be with these men, aged in their 80s and 90s, as they were slowly led down to the graves of their mates.

There were many tears for fallen but also burdens of their own to carry. Many years had passed but some things remain raw.

One of the veterans who came along was a man named John Jones. He was one of three coastwatchers who survived in what was then the Gilbert and Ellis Islands. He and the others survived because they were captured early in the war by the Japanese.

Rounded up, beheaded
Unlike his three best friends (they had all signed up together) who were later among 25 rounded up and beheaded.

Jones would weep as he thought of the terror his mates must have felt as they watched their colleagues being beheaded one by one while waiting for their turn. Unimaginable.

Jones had fought NZ authorities pushing for acknowledgement of the slain coastwatchers.

He succeeded and there is now a beautiful monument in their honour. I had got to know him over the years and was immensely fond of him.

We met up many times and when he died in 2017, myself and a fellow journalist, Mike Field, who had also written about him extensively, went to his funeral.

So here we are in the Solomon Islands and I am reminded of my old friend as there are no veterans here today. Too many years have now passed — any still alive would be in their late 90s or older.

So why does it matter 80 years later that we remember this day?

Undercurrents of tension
There are currently undercurrents of tension in the Pacific we would be foolish to ignore. In the three decades of covering the Pacific, a lot of it based in the region, I feel deep unease about what is happening that I’ve never felt before.

China’s reach and influence are growing. While that’s not a bad thing in some areas, there is a flow-down impact on development, democracy, justice, and freedom of speech.

There is a lot of cash and corruption around. My home country of Kiribati is isolated even from its neighbours and this feels very deliberate.

I fear for what is ahead.

So while we think back to the past today, we need to think about what was won — and at what cost — and how we must go forward.

A Japanese sailor has been stabbed at Bloody Ridge in Solomon Islands during a World War II remembrance ceremony in Honiara.

Witnesses say the man, who was part of the Japanese Navy media team, was stabbed in the neck with a pair of scissors.

Bloody Ridge community chief Wesley Ramo said the culprit was from a neighbouring community and was mentally unstable and under the influence.

He was quickly detained by locals and members of the US military present for the ceremony and taken away by police.

The ceremony then continued peacefully.

RNZ Pacific spoke with medical personnel who said the Japanese sailor would require minor stitches but was okay.

Japan’s Consul in Solomon Islands, Nori Yoshida, said it was a very unfortunate event, and they were unclear of the motive but would be following up with police.

Stabbing mars peaceful ceremony
The stabbing has marred what has been a peaceful ceremony to remember those who lost their lives during the battle of Guadalcanal 80 years ago.

The Guadalcanal campaign was the first major land offensive by allied forces against the Empire of Japan.

An estimated 30,000 people died and as many as three quarters of the deaths were from tropical diseases and starvation.

Events started on Sunday as speakers with ties to those who fought and died there spoke of the importance of remembering their fathers and grandfathers.

The Solomon Islands government has declared Bloody Ridge, also known as Edson’s, a national park.

Senior government and military leaders from the United States, New Zealand, Australia and Japan are in Honiara to mark the 80th anniversary of the World War II Battle of Guadalcanal.

Minister of Defence Peeni Henare is leading the New Zealand delegation along with Secretary of Defence Andrew Bridgman and the Commander of the Joint Forces Rear Admiral James Gilmour.

The New Zealand High Commissioner to Solomon Islands, Jonathan Schwass, said New Zealanders from the army, air force and navy “served with distinction in the Solomon Islands between 1942 and 1945”.

“As WWII starts to slip beyond living memory, it is important that we continue to honour people of all nationalities who served and who died here,” he said.

Schwass said the remembrance ceremonies being organised this weekend showed that they were not forgotten.

A series of commemoration events start today.

Schwass said they were a reminder that the ties between New Zealand and Solomon Islands went back far into the past.

Solomon Scouts and CoastWatchers Trust chair Sir Bruce Saunders said filming the stories of those who served the US Marine Forces when they landed on Guadalcanal on 7 August 1942 was under way.

He said Solomon Islands students did not know their own history and he hoped to change that.

More than 25,000 soldiers died in the battle including dozens of Solomon Islanders.

Sir Bruce said the stories of their grandfathers and their role in saving their country needed to be passed down.
