It's going to be another tough week over here as the nation continues to mourn the death of Queen Elizabeth II.

The late monarch left her cherished Balmoral retreat for the last time on Sunday. Thousands of people greeted her coffin as it arrived in Edinburgh after a somber six-hour journey, which saw villages quieten to a whisper as the hearse drove by. Onlookers flooded Edinburgh's Royal Mile, waiting patiently for hours for a glimpse of the royal cortege.

Earlier in the day, well-wishers told a CNN team on the ground that this was "a moment in history" and that the monarch was "very loved in Scotland." One of those to head to the Scottish capital to bid the Queen farewell was Hilary Gemmell. She told CNN: "On Thursday night I definitely had a tear in my eye. I feel like we've lost one of the family."

On Monday, the Queen's coffin will be moved to St. Giles' Cathedral, where it will lie until Tuesday evening. It will then be flown to London on the next leg of its journey toward the funeral on September 19. On Saturday, the King gave an order for a public holiday across the United Kingdom for the day of the funeral.

Wednesday will be a particularly striking day in the carefully planned period of mourning. In what is likely to be an extraordinary moment, London will fall still as a silent procession takes the Queen's coffin from Buckingham Palace to Westminster Hall, where the late monarch will lie in state until the morning of the service.

It's yet another moment that will probably become seared in our collective memory as members of the royal family are set to walk behind the gun carriage carrying their cherished matriarch.

So, what exactly is happening Monday?

At 2:35 p.m. (9:35 a.m. ET), the Queen's coffin will be moved in procession from the Palace of Holyroodhouse, along the Royal Mile to St. Giles' Cathedral for a service of prayer and reflection attended by the King and members of the royal family.
The King will then have an audience with Scottish First Minister Nicola Sturgeon.
Later, Charles III and members of the royal family will mount a vigil at the Queen's coffin at 7:20 p.m. (2:20 p.m. ET).
On Monday morning, King Charles III arrived at Westminster Hall, where both Houses of Parliament expressed their condolences.

How the royal family will say goodbye to their matriarch.

The death of Queen Elizabeth II has set in motion an intricate period of mourning that will culminate with a huge state funeral on September 19 honoring her lifetime of devotion and steadfast service.

Codenamed "Operation London Bridge," arrangements for Britain's longest-serving monarch have been carefully pored over for years by the many agencies involved, with the Queen herself signing off on every single detail before her death. However, these details were kept under wraps until the sitting sovereign, King Charles III, gave it all his final seal of approval.

Here, we've put together a day-by-day guide to what will happen from now until the state funeral.

The Queen's use of soft power has helped keep the United Kingdom together.

Analysis by CNN's International Diplomatic Editor Nic Robertson

When Scots went to the polls to vote on independence from the United Kingdom in September 2014, the role of the Queen came under scrutiny.

At the time, the leader of the Scottish National Party (SNP), Alex Salmond, pledged that if voters backed exiting from the 300-plus year union, Elizabeth II would remain "Queen of Scots."

Polling at the time suggested Salmond accurately gauged the popular mood on the Queen -- 52% wanted to keep her. The question was moot, however, as Salmond famously miscalculated Scotland's mood on independence, which was voted down 55% to 45%.

Of the many lessons of IndyRef 2014 in Scotland, one solid takeaway was that the Queen was not directly part of the problem.

In fact, the Queen was a unifying force, wielding her soft power delicately and discreetly with the singular aim of keeping together the union and the vestiges of the British Empire, the Commonwealth.

While there has been an outpouring of condolences from many parts of the world showing how popular the British monarch was, one question that loomed during her reign now appears to have been answered. Many have speculated over the years whether former British colonies would seek to sever ties with the Crown following her death.

One of the most asked questions we've had since the Queen's death is: What happens to her cherished dogs? Well, we have an answer of sorts. The corgis are being rehomed with the Duke and Duchess of York, a source close to the duke told CNN on Sunday.

The pair, who divorced in 1996, both reside at the Royal Lodge on the Windsor estate. The source told CNN that the duchess bonded with the late monarch over a shared love of dog-walking and horse-riding. Even after her divorce from Prince Andrew, Sarah continued her friendship with the Queen by walking dogs through the Windsor estate, the source added. Find out more on this story here.
