London CNN  — 

Britain’s Queen Elizabeth has undertaken her first engagements since being forced to miss the Remembrance Sunday service over the weekend after spraining her back.

“Her Majesty received General Sir Nicholas Carter at Windsor Castle today upon relinquishing his appointment as Chief of the Defence Staff,” according to Buckingham Palace on Wednesday.

Dressed in an orange, green and white floral dress, the 95-year-old monarch stood to greet the outgoing general in the Oak Room at Windsor Castle.

The Queen warmly welcomed the head of the armed forces as he entered the sitting room, as one of her dogs ran towards him inquisitively. After the pair shook hands, the monarch said it was “rather sad” that he was stepping down, as they started chatting.

Family photographs of the Duke and Duchess of Cambridge, the Duke of Sussex as well as Princesses Beatrice and Eugenie could be seen on display in the background of the room, where the monarch conducts much of her business while in residence at Windsor.

The military audience took place three days after the palace revealed her regret over having to miss the service at the Cenotaph in central London. Prince Charles, who turned 73 on Sunday, laid a wreath at the war memorial on the Queen’s behalf, as in previous years.

The Prince of Wales is currently on a royal tour in Jordan with his wife Camilla – the couple’s first major overseas visit since the start of the pandemic. When asked by Sky News how his mother was, Prince Charles replied: “She’s alright, thank you very much.

“Once you get to 95, it’s not quite as easy as it used to be. It’s bad enough at 73!” he added, while joking about his own recent birthday.

The Queen’s decision to pull out of the service was said to be unrelated to her doctor’s recent advice to rest, a royal source previously told CNN.

British Prime Minister Boris Johnson on Sunday volunteered that the Queen was “very well” when he saw her last week.

The monarch has been forced to skip a number of engagements in the last month. She conducted her last in-person engagement on October 19 hosting a reception for business leaders at Windsor ahead of the COP26 climate conference in Glasgow. The day after, the sovereign abruptly canceled an imminent trip to Northern Ireland and spent a night in hospital for what a spokesman described at the time as “preliminary investigations.”
