On 6 May 2014 all three Queens met up for the first time in Lisbon, Portugal, in preparation for "Queen Mary 2'"s 10th birthday. All three on departure sailed in a one-line formation to Southampton. On 9 May both "Queen Elizabeth" and "Queen Victoria" led in single file, "Queen Mary 2" up the Southampton channel, with both ships docking in a bow to bow formation performing a birthday salute to "Queen Mary 2". Later on, all three sisters gather for a fireworks display in which "Queen Mary 2" led both sisters back down the channel.
