It is common knowledge already that Prince Philip and Prince Charles did not share a very close and tight relationship. It was reported that this dynamic was more apparent during the Prince of Wales' younger years.

They are like "chalk" and "cheese," a royal expert described. The Duke of Edinburgh enjoyed outdoor activities and excelled in various physical endeavors like sports. On the other hand, the Prince of Wales was a shy, sensitive, and emotional boy, who was reported to enjoy the company of his nanny.

While these differences already served as a huge gap in the relationship between Prince Philip and Prince Charles, it was noted that the Duke of Edinburgh made a "bad mistake" that ultimately "damaged" their father-son link.

According to Express UK, Prince Philip was not an academic child. Even so, he attended both Chean and Gordonstoun, which are private schools. 

It was revealed that the young prince was one of the first students who attended and went to Gordonstoun. It was a Scottish boarding school founded by Kurt Hahn, a German education pioneer as per experts.

Based on claims, Kurt Hahn believed that "strength of character" was much more essential than academic excellence. This is why students at Gordonstoun were strengthened through various physical activities. One great example was that students were sent on early morning runs to be followed by a cold shower after.

Prince Philip shared the same belief. He applauded his school for molding him and making him stronger in terms of the dynamic of his character. 

He also wanted his firstborn son to follow his footsteps as per reports. Because of this, he sent Prince Charles to attend Gordonstoun for his early educational years, instead of the Queen Mother's preference of sending the royals to Eton College.

While the Duke of Edinburgh did not wish or want any harm to happen to the Prince of Wales, many experts and analysts deemed his decision as an "error of judgment."

Later on, reports exposed Prince Charles' notions toward his stay at Gordonstoun. As revealed, the Heir Apparent deemed the school as "hell on Earth." Unfortunately, he was repeatedly bullied, and the challenges became too daunting for him. 

Even so, he still saw a silver lining at the end since he mentioned that his experiences at the boarding school became beneficial for him.

On the other hand, Prince Philip's other two sons, Prince Andrew and Prince Edward, later on, revealed that their experiences at Gordonstoun were filled with happy and joyful memories.
