Walter Manny, 1st Baron Manny

Jean le Borgne's epitaph refers to his son Walter as one "qui fut merveilles en armes aux gueres des Anglois".

[3] Manny played a distinguished role in the Scottish wars of Edward III, being present at the Battle of Dupplin Moor and the Siege of Berwick.

When Hennebont was besieged during that War, councillors tried to persuade the Montforts, led by Joanna of Flanders, to surrender to Charles of Blois, nephew of Philip VI of France.

In 1359, he was made a Knight of the Garter, succeeding John, Lord Grey (died 1 September 1359),[9] and at various times he received extensive grants of land both in England and in France.

In 1349 he bought some acres of land near Smithfield, London, which were consecrated as a burying-place where large numbers of the victims of the Black Death were interred; and here he built a chapel, from which the place obtained the name of "Newchurchhaw."

The chapel and ground were bought from Manny by the Bishop of London, Michael Northburgh, who died in 1361 and by his will bequeathed a large sum of money to found there a Carthusian convent.

The bishop's bequest may have contributed to the building and endowment of the house; or possibly, as seems to be implied by a bull granted by Urban VI, in 1378, there were originally two kindred establishments owing their foundation to Northburgh and Manny respectively.

At all events Manny, who died early in 1372, left instructions in his will, dated St Andrew's Day (30 November) 1371, that he was to be buried in the church of the Carthusian monastery founded by himself.
