This was quite possibly the last time we'll ever see Prince Harry entering the witness box, after many years of his high-profile court battles with the press.

And after the tetchy, scratchy, emotional exchanges in the High Court, it's not something that you think he'll miss.

It's been a "horrible experience", he said about this latest court case, now up against Associated Newspapers in his third set-piece legal dispute with a newspaper group.

Towards the end of two hours of questions, he railed against the "disgusting" sense that he wasn't entitled to a private life, and talked of the emotional toll of alleged press intrusion on him and his family.

"They've made my wife's life an absolute misery," he said, voice cracking, in what could be his last ever words in a UK courtroom.

A tall, lean figure, in a dark suit and tie, Prince Harry gave his evidence about what he sees as a lifetime of hounding by the media, which he claimed used unlawful means of gathering information.

His manner showed how personal this was to him, delivering terse and sometimes tense answers, about a series of stories that he said had "commercialised" his private life and those close to him.

It was something that he wanted the court to understand, that he'd been driven to "paranoia" by the constant attention surrounding him and his relationships.

At one point, the judge, Mr Justice Nicklin, intervened to tell Prince Harry that he needed to just answer the questions and not argue back.

Harry was painstakingly polite, but in the way people are when they're actively trying not to shout back.

It is not clear whether his witness box had the same plastic signs that were on other desks with the reminder: "Please address the judge as my lord/my lady."

Prince Harry painted a picture of a private life being surrounded by anxieties about leaks and intrusions, creating distrust and suspicion about those around him.

He batted away suggestions that some of the journalists who had written these stories were part of his friendship circle. When it was suggested that one go to the same nightclubs as him, he snapped back: "Good for her."

Harry presented the court with the big picture view of the distress caused by being hunted down by the press, with accusations that it was a pursuit that had relied on illegal methods.

Opposing him was the patient, emotionless approach of Associated Newspapers' barrister, Antony White, who offered an alternative explanation for the source of the stories, making the case for their legitimate acquisition.

While Prince Harry gave the emotion, the opposing barrister seemed to want to focus on the forensic detail. It was the broadsword versus the laser. Harry, at times, sounded more defensive than the defence.

As a spectacle, it wasn't how a courtroom drama might be expected to appear.

Although Prince Harry was in the "witness box", it really meant he was sitting in a kind of raised wooden area, behind a computer screen and an array of microphones.

The court wasn't one of those historic rooms with lots of mahogany and Victorian furnishings. It was more like a university lecture room kitted out by Ikea, with rows of lawyers surrounded by boxes of folders and papers.

In fact, the style of the courtroom seemed more modern than many of the newspaper stories being discussed. Because so much of this case seemed to revolve around stories written many years ago, in an entirely different era for the tabloid press.

In the public imagination, Harry is perhaps thought of as being forever young, the younger brother and son. But here he was in court, now in his forties, going over stories from all those years ago.

This case has many more weeks to run, and both sides will keep arguing their corner.

But from Harry's perspective, he will have survived this moment in court, conveying his sense of moral outrage, while avoiding saying anything that will set new stories about his family running.

After his appearance, Prince Harry said: "Today we reminded the Mail group who is on trial and why."

Both sides will claim to be ahead on points - but so far neither side has really delivered a knock-out blow.

It was once bombshell news that a royal was considering facing questions in court; it was something that hadn't happened in modern times.

For Harry, after so many years of legal action and the visible stress of such court appearances, this might finally be a chapter closing.
