General Gerard Hector "Gerry" de Silva, RWP, VSV, USP (born 31 May 1940) was a senior Sri Lanka Army officer.

[2][3] Gerry de Silva, joined the Ceylon Army on 6 May 1960 as a cadet officer and received his training at Royal Military Academy Sandhurst along with Denzil Kobbekaduwa.

In 1971, Captain de Silva was deployed in counterinsurgency operations in Monaragala[4] during the 1971 Insurrection and thereafter served with the Task Force Anti Illicit Immigration (TaFAII) with the Gemunu Watch.

During his tenure the army launched the Operation Riviresa under the command of Major General Daluwatte which was successful in re-capturing the Jaffna peninsula and pushing the LTTE to the jungles of Wanni with significant loss of men and martial.

de Silva had concerns about capturing the Jaffna peninsula without a land route to supply the large number of troops needed to defend it.
