It was an emotional moment for him and he was seen fighting back tears the best he could.
The loss of Prince Philip has left a hole in the hearts of many admirers and people across the board but it has personally affected the royal family as only a death of a family member could.
And while we all felt the loneliness reflected in the Queen's eye as she sat alone during the funeral, many felt their hearts broken looking at Prince Charles trying his best to fight back his tears.
Prince Charles has always been seen in public as a figure who is calm, collected, and in control of his emotions. But in a moment like this, when walking behind the body of his departed father, even he could not help himself but choke up. It was an expression of the deep grief that he felt inside and yet, while in public, he tried to maintain his demeanor in the most dignified manner.
No one has quite seen him like this before in public and people were sympathetic to his emotions. He has had a lot to bear recently and has even watched his sons grow apart, allegedly, after Prince Harry and Meghan Markle's quite dramatic interview with Oprah. Prince Charles was always a big admirer of his father and he had often publicly appreciated the work Prince Philip did in his lifetime.
It was, therefore, quite obvious that tears welled up inside him as he walked behind his father's body for the very last time. May time heal his wounds, if it ever could.
