In 1889/90 Royal Arsenal entered the FA Cup (in the qualifying rounds) for the first time. As well as that we won our first competitions.
We won the Kent Senior Cup (beating Thanet 3-0) and the Kent Junior Cup. Old Westministers beat us 1-0 in the final of the London Cup before we got our revenge by beating them 3-1 to win the London Charity Cup. The cutting above is scanned from the Daily Graphic of April 7th, 1890.
