During its years as a Naval administration headquarters, the Royal Canadian Navy named Wallis House after Admiral William Parry Wallis.
With his captain severely wounded and his first lieutenant dead, Provo Wallis was left in command of two ships close to the enemy coast, the ships crowded with dead and wounded, and with a host of American prisoners. The Americans were manacled, and both vessels set course for Halifax. The frigates anchored in Halifax Harbour on 6 June to a tumultuous welcome. For his part in the taking of the Chesapeake, Wallis was promoted commander on 9 July 1813.
Wallis was awarded the KCB on 18 May 1860. He was promoted to admiral on 2 March 1863 and served as rear-admiral of the United Kingdom between 1869 and 1870. He filled the distinguished honorary position of vice-admiral of the United Kingdom from 1870 to 1876 and was awarded the GCB on 24 May 1873 and . On 11 Dec. 1877, he obtained his final promotion to Admiral of the Fleet.
Wallis began active service at the age of 14 and received full pay until his death at the age of 100. His career must have been one of the longest in naval history.
