Highlights of Prince Harry's US tour

Prince Harry's tour of the USA has come to an end. On leave from his role as an Apache co-pilot in Afghanistan Harry, 28, undertook his second solo tour, causing 'Harrymania' stateside.

Immediately after his arrival Prince Harry had already created quite a stir by making a surprise appearance at the White House. The excited crowd cheered as non other than Michelle Obama introduced the royal guest. The hordes of supporters, eager to catch a glimpse of Britain's most eligible bachelor, were a constant presence as Prince William's brother carried out a week of official duties.

"If all the women on Capitol Hill were dust bunnies, #princeharry would be a Dyson Vacuum," staff member Chris Mickey tweeted. "Every woman is gone. Every. Single. One."

With the theme of uncle-to-be Harry's tour promoting the rehabilitation of injured American and British troops and publicising his own charities, the Prince was charged with inaugurating the Warrior Games, meeting with victims of Superstorm Sandy and teaming up with David Cameron to promote the 'Best of British' in America.

There were audible gasps as Prince Harry joined Michelle Obama in a surprise appearance at the White House for his first engagement of the tour. Harry's visit had been a closely-guarded secret and around 170 guests were visibly shocked as the handsome royal walked into the room.

"Well, surprise," beamed Michelle as she welcomed the royal guest.

"It is an honour to welcome Prince Harry to the White House today," the First Lady said. "As many of you may know, Prince Harry is a captain in the Army Air Corps in the British armed forces." The reference to his military role received a particularly loud cheer from the guests. 

As soon as the Prince had touched down, 'Harrymania' gripped American and everywhere the young royal went he was followed by hoards of excited fans.

"If all the women on Capitol Hill were dust bunnies, #princeharry would be a Dyson Vacuum," staff member Chris Mickey tweeted. "Every woman is gone. Every. Single. One." 

Harry's tour took on a sombre tone when he paid a moving tribute to US servicemen and women on a solemn visit to Arlington Cemetery, Virginia.

Wearing his Household Cavalry's Blues and Royals No 1 dress uniform with a sky blue Army Air Corps beret, the Apache helicopter pilot's first stop was Section 60 of the historic military cemetery, where soldiers who have lost their lives in recent conflicts such as Iraq and Afghanistan are buried.

"To my comrades-in-arms of the United States of America," read the handwritten card on Harry's wreath. "Who have paid the ultimate sacrifice in the cause of freedom, Captain Henry Wales" 

Swimming champion Missy Franklin had an 18th birthday to remember when Harry joined the crowd in singing "Happy Birthday" to her at the Sanctuary Golf Course in Colorado. Missy, who won four gold medals during London 2012, smiled in delight as the party marked her special day.

"And the perfect way to end my 18th birthday!?" tweeted the happy Olympian. "Meeting Prince Harry! It was a honor meeting him and I had a blast as always." 

The sporty Prince was then tasked with inaugurating the Warrior Games, where wounded servicemen and women from the U.S. and Britain take part in sports competitions.

Not one to watch from the sidelines, Harry joined a team playing sitting volleyball before watched several of the day's events

Harry's day in New York ended with a game of baseball in the famous neighbourhood of Harlem. The royal was supporting the charity Project Coach, an initiative that provides youngsters with personalised coaching opportunities and works alongside the Prince's own Royal Foundation.

"He hit that thing out, all of us were like 'wow!' said thoroughally impressed onlooker Jolitta, 9, "Who thinks that a Prince is going to play baseball?" she said. "Princes are usually in castles or doing something important." 

Harry ended his second solo tour on a high note. The royal scored the winning goal at the fourth annual Senteble Cup Polo Match a game designed to raise funds for his charity, Sentebale. The organisation, which Harry founded in 2004, helps children affected by HIV and Aids in the tiny African country of Lesotho.
