Princess Kate and Prince William spent St. David's Day in Wales.
The Welsh Guards were honored at a ceremony in Windsor.
On his first official duty as ceremonial Colonel, Prince William paid a visit to the Welsh Guards.
In a march and ritual steeped in custom, they brought leeks as a gift.
As the soldiers passed, the Prince of Wales gave a cheery salute to them.
They were introduced to members of the Australian Regiment and their families.
The celebration was a highlight of their Wales-themed week.
Kate's responsibility is similar to the one she has every year on St. Patrick's Day.
Being recent weds and first-time parents, they have a soft spot in their hearts for Wales.
