[2] At London Welsh, Maddock set several club records; he is the only player to score five tries or more in a single match on two separate occasions; once against Ilford Wanderers on 22 September and then performed the feat again against Oxford University on 5 February 1909.

It was a perfect start for Maddock's international career; with the Welsh pack dominating the English to allow the backs ample possession.

[4] Wales built an early lead with tries from Pritchard and Hodges; before Wales' captain Gwyn Nicholls, took the ball, swerved past English three-quarters Hind and Raphael, before drawing in fullback Jackett and releasing the ball to Maddock, who had followed his captain in support, this unselfish play form Nicholl allowed Maddock to score a try on his debut.

[4] Maddock impressed enough to retain his position in the national squad for the remainder of the Championship, and scored his second international try in a win over Scotland; though Wales were denied the title and the Triple Crown after a remarkable performance by Ireland at the Balmoral Showgrounds.

The result may have been different, as ten minutes from time, with the score drawn at 3-3, Trew attempted a drop kick at goal, oblivious that Maddock was unmarked at his side, just 15 yards from the try line.

Then in the opening match of the 1907 Home Nations Championship, Morgan retired form international rugby, allowing Maddock to return to the squad.

The first game of the season was against England, and an experimental English pack faltered against their more experienced Welsh counterparts, who utilised a diamond scrummage formation to good effect.

[7] Although two of their regular players were on international duty, Oxford still provided a strong team to face London Welsh.

Oxford started the game at a high tempo, but the Welsh absorbed the pressure and scored three quick tries to lead the University tram 14–6 at half time.
