The 2009–10 season will be the 45th season in the history of Eastbourne Borough Football Club and the 2nd season in the Conference National. This article covers the period from 1 July 2009 to 30 June 2010.
Eastbourne Borough started their first ever season in the Conference National as the underdogs and were tipped to be relegated at the end of the season. Although the first half of the season would have said that they would be back in the Conference South in the next season, having only won two games out of 13, Garry Wilson brought in Plymouth Argyle's promising youngsters Ashley Barnes and Dan Smith and signing Dan Brown from Cambridge United, who brought confidence back into the club which saw them rise to the top half of the table, beating Torquay United and York City in the process. Eastbourne finished their first season 13th in the table with 16 points clear of the relegation zone. A team that had little changed from the previous season, and out of the four summer signings, Simon Wormull managed to stay in the team beyond January, the others Jean-Michel Sigere and Mo Harkin moved across to Farnborough Town and goalkeeper Chris Winterton went to rivals Lewes. There was a small shock to the end of the season, although they had won the Sussex Senior Cup from the current champions Brighton & Hove Albion reserves, goalkeeper Lee Hook and utility player Jay Lovett plus three other players were released of their contracts. This gave Wilson and coach Nick Greenwood more time to sign new players for the new season unlike the rushed signings they made last year. In May, goalkeeper Danny Knowles and striker Liam Marum from Woking, signed to Eastbourne ready for their second season in the top flight of non-league football, a day later Dan Smith signed to Eastbourne from Plymouth Argyle.England Schoolboy international, Simon Johnson, joined the first team from the under-18's squad, followed by Gary Elphick a week later, from Havant & Waterlooville, and Simon Weatherstone.Simon Wormull left Eastbourne in June 2009, making all of last seasons summer signings leaving the club.
A 2-0 win over Kidderminster was their first away win of the season, goals coming from Nathan Crabb and Jamie Taylor. The team then lost the following away game, 2-0, with Stevenage. Their first home game in September saw a 1-1 draw with Chester City, Andy Atkin scoring from a poor back pass. Eastbourne struggled to score past Oxford United and lost 4-0 to the league leaders. The next home game was their second home win against Hayes and Yeading in which Liam Evers-Marum scored two goals in the 3-1 win. Liam scored his third goal in the next game against Tamworth which ended 1-1. This was then followed with a 2-0 defeat away to a 10-man Histon team.
Midfielder Dan Smith was made available for loan or a permanent move, whilst goalkeeper Michael Jordan and Simon Johnson were available for loan moves.Joe Benjamin joined Eastbourne on a one months loan from Northampton Town, followed a few days later by Welsh Under-19 International striker Kayne McLaggon, from Southampton. Their first game with the loan pair in a 1-0 defeat home to Salisbury in a late minute winner. Their first point in November came against Mansfield Town with a goal from loanee Kayne McLaggon. This was followed by another 1-1 draw at home to Histon, Liam Enver-Marum scoring the goal. The away game to Chester ended up being abandoned after pitch invasions forced the referee to abandon the game.
