After military service in the East India Company’s employ, for which Lord Bessborough evidently sponsored him, Greene returned to Ireland and invested in land in Kilkenny and Waterford. Writing to congratulate Warren Hastings on his acquittal, 30 Apr. 1795, he informed him that he devoted his time to farming.
He did not seek re-election in 1806 when his seat was snatched from Lord Waterford by his competitor at Dungarvan, the Duke of Devonshire. He encouraged Richard Keane to stand as a locum tenens for his son, but nothing came of this plan. The duke’s agent claimed that Greene was ‘extremely unpopular in the town, from his being an harsh landlord, and from his having been long in India he has contracted some very arbitrary habits’. He added a story of Greene’s having cut off the fresh water supply to Dungarvan to avenge his defeat there in 1797. In 1807 he offered his Dungarvan property to Lord Waterford for £60,000.
