Substitute Joshua Osude struck late to earn Hashtag United a dramatic victory over their rivals at the top of the Essex Senior League.
Walthamstow had some early chances as the ball pinged round the box but Hashtag put their bodies on the line to clear the danger.
Harry Honesty had the best chance of the half for Hashtag, forcing a good save after being played in following good hold-up play by George Smith.
The game was lacking clear-cut chances going into the half-time break, but Walthamstow had a great chance to take the lead after the interval.
The Hashtag centre-half misjudged a bounce, allowing James to get a shot away from the edge of the box - however, the Hashtag goalkeeper saved well with his legs.
Both teams opted to make changes in the search for a decisive goal as the game wore on. Gebrai Samrai was introduced for the hosts while Ayodeji Olukoga came on for the visitors.
Both sides threatened from free kicks as darkness descended at Wadham Lodge but key chances remained hard to come by.
Just as it looked as though the points would be shared, Osude - brought on in the 81st minute - struck on the counter-attack.
A missed interception led to a 3-on-2 scenario. Osude fired home into the far corner to send the away fans wild - the goalkeeper couldn’t get a strong enough hand to the powerful effort.
The result cements Hashtag United’s position at the top of the league with 39 points from a possible 45. Walthamstow have been leapfrogged by Saffron Walden Town and Hadley and remain on 35 points. The competition supremacy in the Essex Senior League remains fierce
