England's singles winners were Julie Brown (by 4 and 3 against Mary Sheehy), Katherine Russell (by 2 and 1 over Maria O'Reilly) and Jackie Foster (by 5 and 4 against Irish senior champion Gertie McMullen).
Wickham set the ball rolling for England in the afternoon with a flying start which saw her win four of the first seven holes, losing only the sixth, and then the 11th to see her lead cut to two holes by Catherine Rawthore. Holes 12 to 17 were halved, leaving Wickham the winner.
Last year's Senior British champion Julie Brown lost the 3rd hole to Mary Sheehy but then won four in a row for a three-hole lead. Sheehy won the eighth and ninth to be only one down at the turn. Brown won the 12th, 13th and 15th for victory.
The Russell v O'Reilly was the last match to finish. The English player was two up at the turn after winning the eighth and ninth, then the 11th for a three-hole lead. O'Reilly hit back with wins at the 12th and 13th. Three halves holes followed before Russell clinched a 2 and 1 win by taking the 17th.
New Senior British champion Laura Webb was in impressive form against Karen Jobling. The Berkshire-based Iris player lost the second hole but won the next five to be four up at the turn. Webb added the 10th to her collection for a five-hole lead.
Jobling stopped the rot by winning the 11th and 12th but there was no holding Webb in this form. She won the 13th and 14th for the match.
Ireland's Gertie McMullen does not lose many matches by 5 and 4 but she did this afternoon with Jackie Foster her conqueror. There was no hint of the eventual margin of victory when Foster turned with a one-hole lead but the English player slipped up a gear to take the 11th, 12th, 13th and 14th for victory.
Scotland scored their first win for at least two years, beating Wales 5-3 in their first match after losing all three 12 months ago.

Wales' two winners in the singles were Jane Rees, who beat Sheena Wood 3 and 2 n the lead-off tie, and former Senior British champion Ann Lewis, a 3 and 2 winner over Lorna McKinlay. All square at the turn, Rees went two up on Wood by winning the 10th and 13th. The Scot won the 14th to be only one down but Rees took the 15th and 16th for the match.
Kyle was one up at the turn against Richards and went up at the 12th. Richards rallied to win the 13th to be only one down but halves at the 14th and 15th gave Kyle some breathing space and the Scot won the 16th and halved the 17th for a 2 and 1 win, her second of the day.
McKinlay was two up after nine against Lewis but the Welsh player went to town on the inward half, winning the 11th and 12th to square the contest and then taking the 13th, 14th and 16th for a 3 and 2 victory.
Lloyd won the sixth, 10th and 12th for a two-hole lead over Davies. The Scot then won the 14th to be three up. Davies won the 15th to be two down with three to play but she ran out of holes as Lloyd won on the 17th green.
Roberts won the ninth and 10th to square her match against De Vries. The next three holes were halved before De Vries edged ahead again by winning the 14th.
The 15th was halved. Then De Vries won the 16th to be dormie and she won by 2 and 1 to clinch Scotland's 5-3 victory.

Hosts Scotland, who finished pointless last year at Elm Park GC, Dublin, lead Wales 2-1 after the opening session of play.
The morning started in wet, miserable conditions but by lunchtime the sun had come out although a half-gale had replaced the rain.
Scotland's lead-off pair of Sheena Wood and Gillian Kyle beat Ann Lewis and Sharon Roberts by one hole with a very strong finish to overcome a two-hole deficit through the 11th to the 14th.
The Scots won the 15th to halve the Welsh lead and then squared the match at the next which Wood and Kyle won with a birdie 4. After a half in 3s at the short 17th, Scotland won the last hole for the match, Lewis and Roberts conceding it.
Fiona De Vries and Lesley Lloyd put a second point on the board for Scotland with a 4 and 2 win over Chris Harries and Patricia Fernon.
The first six or seven holes were evenly contested but the Scots took a grip on the match by winning the eighth and the 10th to carry a three-hole lead into early holes after the turn.
De Vries and Lloyd went four up with par at the short 14th and though they lost the 15th to a par, the Scots won the 16th with a birdie 4 for a 4 and 2 victory.
Wales' morning winners were Denise Richards and Jane Rees who chalked up a 7 and 6 victory over Alex Glennie and Mary Smith.
The Welsh pair dominated the match right from the start with wins at the first, third, fourth and fifth to be four up on the sixth tee. That became a five-hole lead with a birdie by Richards and Rees at the eighth. The Welsh pair finished off the one-sided match by winning the 10th and the 12th.
Jackie Foster and Catherine Rawthore put England one up against Ireland by beating Gertie McMullen and Maria O'Reilly by two holes.
The English pair were pulled back to square after winning the third and fourth for an early two-hole lead. McMullen and O'Reilly hit by taking the fifth and sixth holes.
But Foster and Rawthore had re-established a two-hole lead by the turn, having won the eighth and ninth but they could not shake off the Irish challenge as McMullen and O'Reilly won the 13th and 15th to square the match once again.
In a tight finish the English pair went one up again with a 2 at the short 17th and a par 4 at the last hole was good enough to give them a two-hole victory.
Julie Brown and Aileen Greenfield made it 2-0 for England with a one-hole win over Carol Wickham and Sheena McElroy.
There was only one hole in it either way in a keenly contested outward half but Brown and Greenfield, one up at the turn, won the 10th and 11th with birdie 4s to be three up. Wickham and McElroy rallied to win the 14th with a par 3 and the 15th with another par to be only one down with four to play. Brown and Greenfield held them at bay with halves at the last three holes.
Ireland's Senior British Ladies champion Laura Webb and Suzanne Corcoran salvaged half a point from the last of the morning ties against Helen Lowe and Karen Jobling ... but it might well have been a win.
The English pair were one up at the turn but lost the 11th to a birdie and went one down for the first time when Webb and Corcoran's par 3 was good enough to win the short 14th.
The Irish pair doubled their advantage with a par 4 at the 15th but Lowe and Jobling finished well to gain a halved match. They won the 16th with a birdie 4 and the 18th with a par 4 to share the honours.
